arLCD touchscreen demo showing how to switch screens and display different programs. The first sketch is an design tool for choosing the colors for the screen layout. The second app is a thermostat using a thermistor to read the current temperature and turn on/off an led. Prototyped on a breadboard. Inspired and enabled by the Detroit Maker Fair.
