Required parts: Solar cell, microcontroller (µC), piezo sounder, wire jumpers

How it works: The controller

requires 2-5V to operate. This

voltage is supplied by the solar

panel. The microcontroller is pre

-programmed with software that

generates a realistic cricket

chirp. The chirp signal is output

via pin 4. The electrical signal is

converted to sound via the piezo

speaker.
