hello guys i made a remote fan regulator.today i attach it to wall and connected to fan.its working fine except its IR sensor activates by CFL in my room(doesnt give any problem f i use incandesent light).i use VS1838 IR receiver.and i dont send data only single pulse to activate.somehow CFL light interfears with sensor.any idea how to overcome this?

thanks

Yes, as suggested in your previous thread remote Fan controller help use an encoded IR signal. I advised you in that thread that you would have problems if you used only the pulse of IR in a room with a flouresnt light fixture.

Build a 'real' remote, your existing one will respond to any source of modulated IR.

fixed it added a pull up resistor and now works fine
