The two most popular kinds of transistors you might use for a project are either BJTs or MOSFETs.  With so many options, it was tough to pick just a few.  

We covered the 2n3904 in this video.  What BJTs are your favorites and why?  Leave a comment below.

Transistors are electronic switches that are used to control things that would kill an Arduino, Raspberry Pi, or Beaglebone.  There are two major types known as a BJT and MOSFET.  This is part 1 of a two part series, which looks at BJTs first.

Learn what they are and how to use them.

Don’t forget to subscribe to the AddOhms YouTube channel to know when Part 2 on MOSFETs is released!

    I James, this is Carlos, from Portugal, do you have any information about a Mosfet ref. CMU06N02N 1209? It’s a Mosfet to control a DC motor for an RC unit.Thanks in advance and congratulations for your excelent way of teaching.Regards.Carlos
