Infrared Light Switch

Inexpensive receivers for standard infrared remote control units for television sets and video recorders are available in the form of integrated circuits. Normally, a computer or microcontroller looks after decoding the light signals. However, this circuit shows that there are alternatives. It reacts to an IR signal, or at least to a signal sent with a carrier frequency of 36 kHz (other types of ICs are available for other frequencies).
