GameBoy Analog Meter

Here’s an interesting setup using a GameBoy Advance as an interface and power supply for a PIC microprocessor. He’s got the PIC connected to the serial port of the GameBoy Advance and is able to pass and retrieve data for display on the screen. You can see above that he is showing two analog values from the pic. You can download the schematic and source code and see a few more pictures, but that’s about it.
