An Arduino Uno provides the processing power and drives the serial monitor. A joystick and a Hitachi H48C accelerometer are mounted on a breadboard and wired to the Uno.

Connect the Arduino to your computer using the USB cable. Open the Serial Monitor in your IDE to see the values from the sensor – this will also help you to calibrate your plant monitor.

This hack takes advantage of all of these aspects to bring you an Arduino controlled CGA monitor. One problem with experimenting with one of these monitors is that they are not that well documented.
