sm0038 definitely works with the tv remote control. connect pin1 gnd pin2 vcc and connect a led with the resister in pin3 when you face the remote control and press any button you can see the led turn on
did not work. when the receiver is not connected then it shows 5v in inverting pin and when transmitter is kept face to face then also the value does not changes. it keeps on showing 2v at the output pin.
can the above circuit be checked using led it the obstacle is being detected or not...if yes how
