Arduino Starter Kit example
Project 14 - Tweak the Arduino Logo
This sketch is written to accompany Project 14 in the Arduino Starter Kit
Parts required:
- 10 kilohm potentiometer
Software required:
- Processing (3.0 or newer) https://processing.org/
- Active Internet connection
created 18 Sep 2012
