ir detector
General Idea:
An IR signal is “seen” by a reverse biased IR diode which produces an electrical signal according to the light intensity. This signal is then amplified trough a transistor which powers an ordinary LED. This means that the LED will light up when the IR diodes receives some IR light (from a TV remote for instance).
