Description

A pair of leds will flash momentarily whenever someone makes a loud noise. The led intensity depends on the sound level. The leds fade out smoothly. A simple sound sensor detects the sound level. A PICAXE 08M2 reads the sound level and drives two leds with pwm. Detailed schematics and source code are on my website.
