[Hounjini] was poking around at the Game Boy Advanced bus of his Nintendo DS lite and figured out how to use it to connect an Arduino to the DS. For testing he’s soldered an IDC plug to the c… ...

Want to know how those serial communications work? He explains that in detail. He also outlines the process of scaling up from the 4 servo demo to 12 servos on a standard Arduino.

The circuit on the left can interface with any one of those, plus any 5V logic signal if a dc voltage of 5, 12 or 24V is also available.

The circuit on the left can interface with any one of those, plus any 5V logic signal if a dc voltage of 5, 12 or 24V is also available. 16mA has been chosen for the led current to match the drive ...

The iolinker interface board has been created by Julian von Mendel based in Donauwörth, Germany and allows you to self-test and rewire your circuitry or use your own FPGA code.
