Electronics Basics

This is a series of electronics courses & workshops. You will learn about the basics of electronics and how to analyze circuits.  You will learn about passive and basic semiconductor components including how to properly work with LEDs.  Additional classes will cover transistors and FETs, linear and switching power-supplies, datasheets, and operational amplifiers. All these workshops include a combination of lecture and hands-on exercises.
