to summarize: designed a 555 timer astable circuit to pulse an IR led at 38Khz. Then placed a 38Khz IR reciever RIGHT infront of it. I cant get a steady reading out of the reciever. Im supplying it with 5V and its outputing like 3V. The reciever is placed directly opposite to the IR led. has the reciever gone bad? Caz, ideally, if it should detect an IR input, it should output some voltage (dont know at which level) and if it doesnt it should output zero. I tred dimming out the lights and placing a aluminum foil in between the led and the reciever and then measure so that i could account for ambient lighting. Still the same confusion. Whats going on? Please help!!!
