Aim: Control a slot machine with OSC messages

Hardware

• Arduino
• Ethernet shield
• 4 x ULM2003 for controlling the stepper motor
• slot machine wheel (they were a donation, no idea where it came from)
• 24 Volt power

Schematic

We used the following schematic found on the arduino site:

http://arduino.cc/en/Reference/StepperUnipolarCircuit

We have 4 stepper motors so we had to have 4 of these. Connect the motors to the right pins of the ULN2003 and the hardware part should be done.

Software

• Z_OSC libary for the OSC messages

You can download the code we used at github

TODO

• Automatich adjustment if device is powered on. There are light switches on the slot machine, have to connect them to the Arduino and use them.
• add button to play with it if there are no OSC messages
