Instructables

Step 3: All put together

Once you have the PCB done, solder it all up and program the chip with your fav. programmer. HEX file attached.

For debugging, you can connect pin 2 (GPIO5) and a ground pin to the serial port of a PC's Rx and ground @ 9600 baud to see the actual tag values and what the chip is doing.  However, it may not work properly on all PC's without the addition of a max232 chip as it is only pseudo RS232 and not true levels.  Not that i have come across any in recent times.
