This is part of the starter blog for Transistor Basics. Check out here to see all of them. ~What you need~ N-P-N Transistor( BC-547)–> 2 2 resistors (110K ohms+270 ohms) 1 LED 1 Breadboard Few breadboard connecting wires 9V Power
Transistor circuits that we are going to make will use a 5V power supply. We somehow need to turn the 9V battery usually available in market to give us a 5V supply. We are going to use the 7805 IC for that. Lets get started!
Once you have got our hands on an Arduino, to start working on it, of course we would have to set it up and it’s software (IDE)! Lets get started!
