In this video, I will explain the working of the transistor timer circuit, also known as delay timer or turn on circuit, which is an example of a hobby electronic circuit that you can easily make on a breadboard and make using basic circuit elements such as BJT transistors, capacitors, LEDs, resistors and buttons. This example will be extremely useful in terms of better understanding the principle of BJT Transistor and capacitor working together. For a better understanding, I recommend that you consider the video as a whole and watch it until the end. If you watch the video until the end, you will better understand the logic of the capacitor's operation in DC. I will also show a simulation of this circuit with Proteus towards the end of the video.
