Voting Pads Using AVR Over RS-485

This integrated voting system includes several touch pads that feature an ATmega88, a MAX485, a few LEDs, and push buttons. The keypads communicate over the RS-485 bus. A Java application runs on a PC that generates a bar graph similar to one seen on TV game shows.
