Twitter controlled maze game
by Diego Vega
Objective:
To create a visual maze game that will be controlled by many users sending commands via Twitter. The game will use Arduino’s potentiometer as input to modify the color of the background of the maze.
Materials:
- Arduino Uno
- Computer
- Arduino IDE
- Processing IDE
- Data Cable
- Potentiometer
- Jumper Wires
- Twitter account
Set up:
Commands:
#ART150Maze down
#ART150Maze up
#ART150Maze left
#ART150Maze right
