Welcome to the projects area. There will be all things related to various projects past, present and future.

Code, hints and tips can be found here along with item descriptions and uses.

Transistors

Bipolar Junction Transistors (BJTs)

Bipolar Junstion Transistors are the standard type of transistor, also known as bipolar transistor.

A BJT has three connections:

  • Base
  • Collector
  • Emittor

There are two types of BJT:

  • NPN
  • PNP

A basic bipolar transistor

There is another type of transistor available...

MOSFETs

The Metal Oxide Semiconductor Field Effect Transistor, or MOSFET, is an improvement on the BJT in many ways. It is a high impedance device that uses a low voltage to switch it on.

As with a BJT a MOSFET has three connections

  • Gate
  • Drain
  • Source
