If you want to learn electronics in a simple way. The electronic circuit is the combination of electronic devices with conductors. Then, the electronic circuit experiment makes you learn electronics with fun. And understand the work easier.
In one electronic circuit may consist of several small electronic circuits to work together. Also, in one of our problems. There are many ways to choose the several circuits.
For example: if we need to create a 2 LED flasher. We can choose. Transistors, IC-555, CMOS Digital-ICs, CD4011, CD4049, OP-AMP ICs, LM324, LM741, and more.
Or even, a micro controller. Such as the PIC Micro controller, and Auduino micro controllers, etc. Thus, the collection of many electronic circuits. It is very helpful. You can choose the most suitable circuit as conditions or resources.
If you are looking for the electronics circuit. We also like to collect the many electronic circuits. You may start with a simple circuit first. Let’s get them here!
