CLAP SWITCH
PART NO. 2221376
The kit gives the logic used to make a hardware-only clap-on, clap off circuit. This circuit employs some very simple and cheap circuitry,
and a simple program. It is relatively easy to make a hardware only clap on/off circuit, but I wanted to create a circuit that required two
claps to switch on, and two claps to switch off. The claps must be in quick succession. This device can be thrown together in a single
evening.
