In order to master my Raspberry Pi I/O projects, I want to create a GUI-based tool to control all possible I/O devices.
So far I have been experimenting with:
Adafruit 16-channel i2c PWM breakout for servos
Stepper motor
USB Missile Launcher (Dream Cheeky Thunder)
So my first attempts will be to add these in a graphical interface. I am using pygtk on the Raspberry Pi.
