Simple remote controlled light relay.

Status: Done, in use.

Simple one channel remote controlled relay for controlling lamps. The lamp toggles on or off using a Philips RC5 remote control (other protocol can easily be added), and which to use is hardcoded into the firmware. After eight hours, the relay are automatically turned off.

A 12V 2.6VA transformer and a 5V regulator transform the 230VAC to 5VDC. The controller is a PIC16F876 atttached to a 5V relay and a 38KHz IR-reciver.
