SAR (Sound Activated Robot) by Steven Frye

SAR is a robot that uses a sound activated circuit from to run a 1.5-3vdc motor
with a weigth on it to vibrate and move when it hears a sound.Also SAR has three blinking red LEDs
for looks and is powerd by two AA batteries.Sar didnt cost much to build all I had to buy was the
sound activated circuit and the three red blinking LEDs everything else came from my junk heap.

Time to build:one afternoon and about one hour of the next morning.

This is my fifth robot to build from scratch.
