The 12V and 5V power supply PCB board used in this video is sponsored by the PCBWay Company. For step by step explanation you can watch a video tutorial given at the end of this article. I will also explain the working principle of each electronic circuit, and we will test each circuit on breadboard. In this article, we will develop the same electronic projects using the most popular 2n2222 NPN transistors. Recently some electronic projects got viral which were completely based on the BC547 Transistor. So many amazing electronic projects can be built using this transistor. Electronic projects with 2n2222 Transistor or BC547 Transistor- BC547 NPN Transistor is of the most popular Bipolar Junction Transistors.
