Do you want to learn electronics, so that you can build your own gadgets?
There is a ton of resources on learning electronics – so where do you start?
And what do you actually need?
And in which order?
If you don’t know what you need to learn, you can easily waste a lot of time learning unnecessary things.
And if you skip some of the simple but crucial first steps, you’ll struggle with even the basic circuits for a long time.
If your goal is to be able to build your own ideas with electronics, then this checklist is for you.
When you follow the checklist below, you will get up to speed fast – even if you have no experience from before.
While some of these steps might take you a weekend to tackle, others can be done in less than an hour – if you find the right teaching material.
Start by reading through all the steps all the way to the end to get an overview.
Next, decide what teaching material you will use to tackle each step.
Then start to learn electronics.
Step 1: Learn the Closed Loop
If you don’t know what is needed for a circuit to work, how can you build circuits?
The very first thing to learn is the closed loop.
It’s essential to make a circuit work.
After finishing this step you should know how to make a simple circuit work. And you should be able fix one of the most common mistakes in a circuit – a missing connection.
This is simple, but necessary knowledge to have when learning electronics.
Step 2: Get a Basic Understanding of Voltage, Current and Resistance
Current flows, resistance resists, voltage pushes.
And they all affect each other.
This is important to know to learn electronics properly.
Understand how they work in a circuit and you will have this step nailed.
But, there’s no need to dive deep into Ohm’s law – this step can be learned through simple cartoons.
After finishing this step, you should be able to look at a very simple circuit and understand how the current flows and how the voltage is divided among the components.
Step 3: Learn Electronics By Building Circuits From Circuit Diagrams
No need to wait no more – you should start building circuits now. Not just because it’s fun, but also because this is what you want to learn to do well.
If you want to learn to swim, you have to practice swimming. It’s the same with electronics.
After finishing this step you should know how circuit diagrams work and how to use a breadboard to build circuits from them.
You can find free circuit diagrams for almost anything online – radios, MP3 players, garage openers – and now you’ll be in a position to build them!
Step 4: Get a Basic Understanding of These Components
The most common components you’ll see in the beginning when learning electronics are:
- The resistor
- The LED
- The capacitor
- The transistor
You can get a basic understanding of each of these quickly, as long as you have good learning materials.
But take note of that last statement “as long as you have good learning material” – because there is a lot of terrible learning material out there.
After completing this step you should know how these components work and what they do in a circuit.
You should be able to look at a simple circuit diagram and think:
“Aha, this circuit does this!”.
Step 5: Get Experience Using the Transistor as a Switch
The transistor is the most important single component in electronics.
In the previous step you got an intro to how it works. Now it’s time to use it.
Build several different circuits where the transistor acts as a switch. Like the LDR circuit.
After completing this step you should know how to control things like motors, buzzers or lights with the transistor.
And you should know how you can use the transistor to sense things like temperature or light.
Step 6: Learn How To Solder
Prototypes built on a breadboard are easy and quick to build. But they don’t look good and the connections can easily fall out.
If you want to build gadgets that look good and last for a long time, you need to solder.
Soldering is fun, and it’s easy to learn.
After completing this step you should know how to make a good solder joint – so that you can create your own devices that look good and will last for a long time.
Step 7: Learn How Diodes and Capacitors Behave in a Circuit
At this point you will have a good foundation of the basics, and you can build circuits.
But your efforts to learn electronics should not stop here.
Now it’s time to learn to see how more complicated circuits work.
After completing this step – if you see a circuit diagram with a resistor, a capacitor and a diode connected in some way – you should be able to see what will happen with the voltages and currents when you connect the battery, so that you can understand what the circuit does.
Note: If you can also understand how the Astable Multivibrator works, then you’ve come a long way. But don’t worry too much about it, most explanations of this circuit are terrible.
Step 8: Build Circuits Using Integrated Circuits
Up until now you’ve been using single components to build some fun and simple circuits. But you’re still limited to the very basic functions.
How can you add cool functionality to your projects, like sound, memory, intelligence and more?
Then you need to learn to use Integrated Circuits (ICs).
These circuits can look very complex and difficult, but it’s not that hard once you learn the right way to use them. And it will open up a whole new world for you!
After completing this step you should know the steps for using any integrated circuit.
Step 9: Design Your Own Circuit Board
At this point you should have built quite a few circuits.
And you may find yourself a bit limited because some of the circuits you want to build requires a lot of connections.
To learn electronics properly, you should definitely do this step.
Now is the time to learn how to create your own circuit boards!
You can start with a simple program such as Fritzing to get started. If that is not sufficient for your needs, learn a more advanced PCB design software such as Eagle or KiCad.
After completing this step you should know how to design a PCB on a computer, and how to order cheap PCB prototypes of your design online.
Step 10: Learn To Use Microcontrollers In Your Projects
With integrated circuits and your own custom PCB design you can do a lot.
But still, if you want to really be free to build whatever you want, you need to learn to use microcontrollers. It will really take your projects to the next level.
Learn to use a microcontroller, and you can create advanced functionality with a few lines of codes instead of using a huge circuit of components to do the same.
After finishing this step you should know how to use a microcontroller in a project, and you will know where to find information to learn more.
Do you want this step-by-step checklist in PDF format to see the exact steps I recommend to learn electronics from scratch?
Need Help With Any of the Steps?
With this checklist you can learn electronics on your own. You are free to find your own learning material from anywhere you want.
You can find information in books, articles and courses to help you on your journey.
I recommend finding someone who has a teaching style that you enjoy – and avoid those that teaches in ways you don’t enjoy.
