Starting Electronics in 2026? Here's What you Actually Need!(原声文稿)
If you're starting your electronics journey, don't make the mistake of buying every tool you see online.
You only need a few things to get started and we'll show you exactly what to buy and in which order.
So the first tool every beginner should have is a breadboard. It lets you build electronic circuits without any soldering.
You simply insert components like resistors, sensors, or even a microcontroller.
Connect them using jumper wires and your circuit is ready to test.
The biggest advantage is that nothing is permanent. component.
If you make a mistake, which you definitely will while learning, you simply pull the component out, reconnect it correctly, and you're good to go. Now breadboards come in different sizes. You'll find mini -breadboards, half -sized breadboards, and full -sized breadboards.
For most beginners, I'd recommend buying a full -sized breadboard.
It gives you plenty of space to build circuits, and you won't outgrow it anytime soon. One more thing I'd recommend is buying a good quality breadboard.
Very cheap ones often have loose contacts that don't hold components properly, leading to poor electrical connections and frustrating troubleshooting.
You use jumper wires to connect different components on your breadboard.
Now you'll generally come across three types, male to male, male to female, and female to female.
Instead of buying them separately, I'd recommend getting a kit that includes all three.
They're inexpensive and sooner or later you'll end up using each type.
You can also get a box of pre -cut wires that comes in different sizes. It makes your circuit look more clean and easy to detect errors.
When you've built your circuit on the breadboard, the next step is to power it.
The simplest option is a 9V battery like this one. You might know it as a transistor battery.
It's been a staple in hobby electronics for decades, and I've used these countless times for powering small circuits and projects. The other option is to use AA battery holders.
You can get a single, two, three, or even four cell battery holders.
This gives you the option of having different fixed voltages. Now using batteries is fine.
They work, but they don't last very long, and replacing them again and again can quickly become expensive.
A much better option is to use one of these breadboard power supply modules along with a 9V or 12V DC adapter.
The module plugs directly into your breadboard and converts the input voltage from the adapter into a stable 3 .3V or 5V supply, which is what most electronic circuits require.
Depending on your circuit, you can easily select either 3 .3V or 5V using these jumpers.
As you learn electronics, you'll be building dozens of small circuits using different electronic components.
Having a component kit on your desk means you can simply pick the parts you need and start building in an easy way.
My advice is to buy a kit that has a good variety of components, rather than one with thousands of pieces. sizes.
A smaller kit with useful components is much more valuable than a huge kit filled with parts you'll probably never use.
If there's one tool I would never recommend skipping, it's this one.
A multimeter is one of the most important tools in electronics because it lets you measure and troubleshoot your circuits instead of simply guessing what's wrong.
With it, you can measure voltage, current, and resistance, check whether two points are electrically connected using the continuity mode, and even test components like diodes. units.
Some multimeters can also measure capacitance, frequency, temperature, and much more. You don't need an expensive multimeter to get started.
Even a basic digital multimeter is more than enough for learning electronics and building beginner projects. But please never buy those ultra -cheap yellow multimeters.
They're less accurate, have poor quality test probes, and lack the internal safety fuses needed to protect you if you accidentally turn the dial to the wrong setting.
Next, let's talk about some basic hand tools that are really useful. The first one is a wire cutter.
Whether you're trimming resistor leads, cutting hookup wires, or shortening header pins, a good flush cutter gives you a clean cut and makes your work much easier. The second tool is a wire stripper.
Whenever you need to remove the insulation from a wire, a wire stripper does the job quickly without damaging the conductor inside.
You can either go for a simple wire stripper like this one, which costs less than a dollar, or get a self -adjusting wire stripper that works with different wire sizes. The next tool I'd recommend is a screwdriver set.
You might not think of screwdrivers as electronics tools, but you'll be surprised how often you'll need them.
Whether you're opening electronic devices, tightening terminal blocks, assembling enclosures, mounting development boards, or working with sensors and modules, having the right screwdriver makes the job much easier.
It's a simple tool, but one that you'll probably use just as often as your wire cutters.
And finally, tweezers.
They may not seem important at first, but but once you start working with small components, tight breadboard layouts or SMD parts, you'll quickly realize how useful they are.
And finally, I want to show you one tool that many beginners don't know about, but it's surprisingly useful, a multi -function component tester.
As you start working with more electronic components, there will be times when you don't know exactly what a component is, whether it's working properly or even which pin is which.
This little device can help with all of that.
Simply insert the component into the tester, press a button, and within a few seconds it can identify components like resistors, capacitors, diodes, transistors, and much more. Now, is this a tool that every beginner absolutely needs?
No, you can definitely learn electronics without it.
But considering how affordable these testers have become, they can save you a lot of time and remove a lot of guesswork, especially when you're working with loose components or salvaging parts from old circuit boards.
One thing I will recommend you to definitely buy is a microcontroller board.
You might not use it when you're just starting out, and that's completely fine.
But if you keep building electronics projects, sooner or later you'll want to add some intelligence or automation to your circuits.
Think of it as the brain of your electronic projects that you can program to perform tasks.
It allows you to read inputs from sensors, process data, and control outputs like motors, displays, relays, and much more. There are plenty of excellent development boards available today.
You've probably heard of Arduino, ESP32, and the Raspberry Pi Pico.
Each one has its own strengths, and honestly any of them is a great place to start.
And the good news is you can get most of these for under $10.
So don't spend too much time worrying about which board is the absolute best.
A breadboard power supply or a battery are great ways to start with basic projects, but as you gain more experience, you'll find that while prototyping, you need an easy way to adjust the voltage and see how your circuit behaves. That's where a bench power supply comes in. But that's only half the story. One of its biggest advantages is current limiting.
Let's say you've accidentally made a wiring mistake or there's a short circuit in your project.
If you're using a regular power adapter, it will try to supply as much current as it can, which can damage your components.
A bench power supply lets you set a maximum current limit.
If your circuit tries to draw more than that, the power supply automatically limits the current, helping protect your components while you troubleshoot the problem.
I also use it almost every time I want to test a new circuit.
Instead of searching for batteries or different power adapters, I simply connect to the circuit, set the required voltage, adjust the current limit, and start testing. Now you don't need a fancy bench power supply.
A decent adjustable one with basic safety features is more than enough to get started.
I'd also recommend getting one with a digital display so you can clearly see both the output voltage and the current your circuit is drawing.
The one I have cost me around $40 and it can supply up to 30 volts and 10 amperes with adjustable constant voltage and constant current modes.
That's already more than enough for most hobby electronics projects.
If there's one skill that every electronics enthusiast should learn, it's soldering.
Once you know how to solder properly, you can build permanent circuits, repair electronics, replace faulty components, and even design your own hardware.
Now, if you're buying your first soldering iron, I highly recommend getting a temperature controlled soldering station instead of the cheapest fixed temperature iron you can find.
With a temperature controlled iron, you can adjust the temperature depending on the component you're soldering, which gives you much better results and also reduces the risk of damaging sensitive components.
You'll also notice that soldering irons come with different tip shapes.
For most electronics work, a chisel tip is the best all -round choice.
It transfers heat more efficiently than a very fine conical tip and makes soldering much easier, especially for beginners.
A good soldering iron might cost a little more, but it's a tool you'll probably use for many years, so it's worth investing in a decent one right from the beginning. A soldering iron alone isn't enough. You'll also need solder wire. Solder is what creates the electrical and mechanical connection between components and the PCB.
It melts when heated by the soldering iron and solidifies to form a strong joint.
Now you'll mainly come across two types of solder wire, leaded and lead -free.
Leaded solder melts at a lower temperature and is generally easier to work with, width, which is why many hobbyists prefer it.
Lead -free solder, on the other hand, is more environmentally friendly, costly, and is commonly used in commercial electronics.
When buying solder wire, pay attention to the diameter.
For general electronics work, look for something around 0 .8 to 1mm.
Anything thicker makes it hard to control the amount of heat and solder going into small joints.
Another thing to look for is flux core solder.
Most good quality solder wire already has flux inside it, which helps the solder flow smoothly and gives you properly wetted reliable joints.
Flux helps remove oxidation from the metal surfaces and improves solder flow, and you'll find it especially useful when you're working with old components, large connectors, or trying to fix a poor solder joint.
I have flux in paste form, but it also comes in liquid, gel, and even flux pens.
Another tool that makes soldering much easier is a helping hands or a PCB holder.
When you're soldering, one hand is holding the soldering iron, and the other is holding the solder wire.
That doesn't leave you with a free hand to hold the circuit board.
A helping hands tool uses adjustable arms with small clips to hold your PCB or components in place.
Many models also include a magnifying glass, which can be useful when working with small components.
A PCB holder, on the other hand, is specifically designed to securely grip the circuit board and keep it stable while you solder. You can also rotate the PCB, which makes it easier to access different parts of the board.
It is generally more expensive than basic helping hands tool, so if you're just getting started, a basic helping hands tool is perfectly fine.
Remember the breadboard we started with?
A breadboard is perfect for testing and experimenting with your circuits, but once you're happy with the design, the next step is to make it permanent.
That's where a perf board comes in.
A perf board is a board with a grid of holes usually spaced 0 .1 inches apart.
This allows you to solder your components together using point -to -point wiring.
Unlike a breadboard, the components won't come loose when you move the circuit around.
Perf boards are inexpensive, available in different sizes, and are perfect for prototypes, DIY projects, and one -off builds.
In fact, before designing a custom PCB, many hobbyists first build their final circuit on a Perf board to make sure everything works as expected.
Now, no matter how careful you are, everyone makes mistakes while soldering.
You might solder the wrong component, accidentally bridge two pins together, or simply need to replace a faulty part. That's where desoldering tools come in. The first one is a desoldering pump.
Once the solder is melted, you simply press the pump and it quickly sucks up the molten solder, making it easy to remove through whole components. The second one is a solder wick.
It's a braided copper strip that absorbs molten solder, making it perfect for cleaning up solder pads, removing excess solder, or fixing solder bridges.
Always apply a little flux before using the wick.
It helps the solder flow into the copper braid more easily, making the desoldering process faster and more effective.
I like keeping both on my workbench because each one has its own purpose.
While working on electronics projects you'll be doing all kinds of things, soldering, cutting wires, assembling circuits and handling small components.
So having a proper work surface is very helpful.
You can get one like this from Amazon for less than $10.
It's made from silicone, so it's heat resistant and durable, while also helping protect your desk from scratches, solder and accidental spills.
It also has multiple compartments where you can keep components, screws and tools organized.
And some sections are magnetic, which is really handy for keeping small screws and other metal parts from getting lost.
The oscilloscope is one of those tools you might not need on day one, but once you start working on more serious electronics, it becomes incredibly useful.
Unlike a multimeter, which gives you a number like voltage or resistance, an oscilloscope lets you actually see what a signal is doing over time.
You can see whether a signal is steady, changing, noisy, oscillating, or behaving completely differently from what you expected.
For example, if a circuit isn't working properly, a multimeter might tell you that there's 10 volts at a particular point.
That's useful, but it doesn't tell you whether that voltage is actually stable or if there's noise or some weird voltage drop happening. An oscilloscope can show you that waveform directly.
You'll mainly use it for things like checking clocks, PWM signals, communication signals, audio signals, power supply ripple, and troubleshooting circuits.
Now, many beginners think oscilloscopes are expensive, but that's no longer true.
These days, you can get compact handheld oscilloscopes as well as entry -level digital oscilloscopes at very reasonable prices.
Like this DSO -138 right here, it costs around $20 and while it has its limitations, you can still use it to visualize waveforms, check signal frequencies, and troubleshoot basic circuits.
I'll put a link to it in the description if you want to check it out.
For most beginners, a two -channel digital oscilloscope with around 50 to 100 megahertz bandwidth is more than enough.
Also pay attention to the sample rate, triggering, and probe quality. These matter more than simply chasing the highest specs.
Another really useful tool to have on your workbench is a signal generator.
A signal generator lets you create different electrical signals, such as sine, square, and triangle waves, with a specific frequency and amplitude.
For example, if you're working on an audio amplifier, you can generate a triangular wave and feed it into the amplifier to see how the circuit responds.
You don't need an expensive signal generator which costs hundreds of dollars.
There are plenty of compact and affordable options available online which are more than sufficient for hobby projects.
This particular one is a small DDS signal generator.
It can generate several different waveforms with the main DDS output covering frequencies from 1 Hertz up to about 65 kilohertz.
It also has a separate high -speed square wave output that can go up to 8 megahertz. You can adjust the frequency, amplitude, and offset.
And the LCD makes it easy to see your settings.
And here's the fun part. This particular one is based on an ATMEGA 16 microcontroller.
And you can actually buy it as a kit and assemble it yourself. It It costs around $30 to $35. But there's an even cheaper option.
You can get a basic function generator for around $5.
It's much simpler, but it's a great low -cost option if you just want to experiment with different waveforms.
The final recommendation isn't an electronic tool at all. It's a storage organizer. When you're just starting out, you probably own a handful of resistors, diodes, and a few sensors.
But as you build more projects, that collection grows surprisingly fast.
Before you know it, you'll have hundreds of capacitors, transistors, jumper wires, and modules scattered across your workbench.
That's why I highly recommend investing in a good storage organizer.
Not only does it keep your workspace clean, but it also saves a tremendous amount of time.
Instead of spending 10 minutes searching for a display or a potentiometer, you'll know exactly where everything is.
There are plenty of options available, from small compartment boxes for components to multi drawer storage cabinets for larger collections.
If you're just starting out, a few compartment organizers are more than enough. And if you happen to have a 3D printer, you can even print your own.
There are thousands of different organizer designs available online, so you can choose one that fits your workspace and the components you have.
