I'm currently playing aound with some IR LEDs and recievers, but the reciever is acting weird. I'm using the simple scematic from this page but whenever i plug 5V into the circuit, the led lights up even if the IR LED isn't activated. It looks like the IR receiver is always letting current trough, even if it doesn't receive an IR signal at its base.
What can be wrong? Is there a possibility that the receiver is broken?
