[QUOTE=KE4NYV]If you anyone is interested, I drew up a four relay board tonight based on a PIC18F252 utilizing the USART and serial comms. I am a hardware guy and not much of a code writer. I am considering having a single board made up to proto and start working on some simple firmware.
you can drop the max232 and just use 2 resistors. its out their, you just tell the sw usart to use inverted signalling.
