Introduction to Using an Arduino
This page is designed to provide an introduction to using Arduinos with simple attachments, such as NeoPixels, Servo Motors and LED strips. This is Lab 5 from Prof. Ludtke's annual introduction to programming class: LectureVideo/IntroProgramming15
The Arduino platform includes a range of small embedded computers designed to provide easy interfacing to a wide range of motors, displays, sensors, etc., at low cost ($5-$50). The processor in an Arduino is not very powerful (typically an 8-16 Mhz 8 bit processor), but it is sufficient for many simple applications (http://playground.arduino.cc/Projects/Ideas). Arduino compatibility has also been added to a number of more powerful processors, such as the BeagleBone Black and Intel Edison.
In this lab, you will have access to a variety of preassembled Arduino-peripheral combinations, with simple exercises for a range of different skill levels.
Everyone should start with this:
When you finish that, pick one of these, and work through it to the end. If you're having fun, you are welcome to do more than one
