There are lots of resources to learn about electronic circuits, so where do you start?
What do you need? In what order?
If you don’t know what you need to learn, it’s a waste of time.
Step 1: learn the closed circuit loop
If you don’t know what circuits need to work, how can you build circuits?
The first thing to learn is a complete circuit, which can work normally, with power supply, line and load. After completing this step, you should know how to make a simple circuit work. You should be able to fix the most common error in the circuit – missing connections. It’s very necessary to understand the knowledge of.
However, there is no need to delve into Ohm’s law and so on. After completing this step, you should be able to draw a very simple circuit to understand how the current flows and how the voltage is distributed between components.
Step 4: basic understanding of these components
When you begin to learn about electronic products, you will see that the most common components include resistance, led, capacitor and transistor
After this step, you should know how these components work and what they do in the circuit.
You should be able to see a simple circuit diagram and think, “the circuit is like this!”.
Transistor is the most important single element in electronics. In the previous step, you learned how it works. Now it’s time to use it.
Build several different circuits where the transistor acts as a switch, such as the circuit diagram of the light controlled switch with a photosensitive resistor (LDR). After completing this step, you should know how to control things like a motor, a buzzer or a crystal tube lamp. You should know how to use transistors to sense things like temperature or light.
