ICs that are for Fun

These integrated circuits are, as we say, just for fun!

Sound

ELM701 – Solid State Mouse
A little circuit that ‘chirps’ at random intervals by way of a piezo element.

Light

ELM711 – Christmas LEDs Driver
Controls 5 strings of LEDs with 16 different patterns. Can either be set to automatically start at power on, or only if commanded by a pushbutton switch.

ELM712 – LED Runner
A circuit to run LEDs sequentially. Combine several to create a ‘chaser’ circuit.
