Hi jerson.

Sorry for late reply, I was out of town. Well I donot have diagram for my IR remote project yet. I am using pic16f628 @ 4mhz. I have connected TSOP1736(IR Sensor) to PORTA.4, remaining ports I am using for switching lamps on/off using optocouplar(MCT2E) and triac(BT136).

Now All I want is to use PWM (or any other method) at PortB.5 and using optocouplar and drive Triac to control speed of fan.

your help is much appreciated.

thanks for ur precious time.
