This is the "brains" of my senior design project, a functional pet door. I hacked the RF modules from some Radio Shack remote control cars for the pet collar transmitters and matching receivers. Used opto-isolators just for fun to separate the motor controls from the RF, PC linking and other logic circuits. This interfaced with the PC ISA 8255 PPI card so I could control, monitor and provide a nice interface for the system.
