An introduction to the MOSFET:
If you need to switch high current and or high voltage loads with a micro controller you’ll need to use some type of transistor. I’m going to be covering how to use a MOSFET since it’s a better option for high power loads. This guide will be just a brief introduction that will discuss how to drive a mosfet in a simple manner with the ultimate goal of making it act like an ideal switch.

I marked this in my RSS feed to read, and then I realized I had already read it, and even commented on it! Huh… where did I see this before? Hackaday?
