Using NPN transistor as a switch
The schematic for the circuit. Using Arduino Uno, 12v led strip, 9v battery and 2N3904 transistor, with some simple code to control on/off. And a
What is BJT transistor – Introduction
There are 2 main types of transitor, namely Bipolar Junction Transistor (BJT) and Field Effect Transistor (FET). Basically both type perform the same function ie.
