Rolling Code 10-Channel UHF Remote Control Kit

Kit 181 uses the same Tx/RX pair as Kit 180 but it uses all 10 defined keypress combinations out of the 4 buttons to activate relays. If you read the technical documention the following keypress combinations give readable outputs: pins 1, 2, 3, and 4 (of course) and the pins 1&2, 1&3, 1&4, 2&3, 2&4, and 3&4 pressed together. A PIC16F628 does ALL the work. It is a perfect demonstartion of how micro-controllers have taken over from cmos logic etc.

Toggle or momentary mode will be determined by keeping the 1 or two buttons depressed for more than 2 seconds and then that relay will stay in that mode until another >2 sec keypress. Small relays are used to save weight and board area. Get the commented source code and object hex file here.
