ELM701 Solid State Mouse Description The ELM701 is a fun circuit for creating mouselike noises. Its very low current consumption makes it an ideal candidate for battery-powered toys and novelty items. All of the logic required for circuit operation is contained within this 8 pin integrated circuit. Normally only a battery, a piezo element, and a single resistor are all that are needed for a plete circuit, although an on/off switch may be desireable. The ELM701 uses pseudo-random number generators to produce from one to four ‘chirps’ at random intervals of up to about eight seconds. This makes the noises seem more like a real (but fairly active) rodent. Between these series of chirps,...
