MOSFET

Introduction to the MOSFET A MOSFET is a Metal Oxide Semiconductor Field Effect Transistor.   That might sound intimidating, but basically, a MOSFET is a switch.  There are two types of MOSFETS:  Enhancement mode, and depletion mode.   Unquestionably, the most common type of FET is the Enhancement mode.    We will Read More »

Transistors

Introduction to Transistors Transistors can act as a switch, or as an amplifier.    Using a transistor, we can control a large load with a small amount of current.  Micropressors, such as the Atmega328 are allowed a maximum of 40mA of current per output pin.   Loads such as a motor, Read More »
