Microcontrollers are tiny computers that are used to control all kinds of devices. Many Maker projects build in microcontrollers like Arduinos and TI MSP430s to control lights and motors, collect data from sensors for robots. These microcontrollers are very popular since they are relatively easy to program without a lot of prior experience.
This tutorial will teach you how to hook up a microcontroller for the first time and write a simple program that can control devices hooked to the microcontroller board. It is designed for people who have very little to no experience using a microcontroller or electronics. By the time you complete the tutorial you will be comfortable writing simple code and hooking devices up to a microcontroller board.
