How to use Transistors (BJT & MOSFET)
Ever wonder how to use BJT or MOSFET transistors? Transistors are amplifiers that allow you to switch relatively high power safely using a low power device like an Arduino or Raspberry Pi. In this tutorial I show you how to use both NPN and PNP Bipolar Junction Transistors as well as N-Channel and P-Channel MOSFETS. I indicate how you might go about choosing the appropriate transistor for your circuit using a datasheet.
