SOUND TO LIGHT CIRCUIT

This kit Model MK103 was purchased from Velleman Electronics for about $10.00. They have very high quality kits and very nice instructions. I plan to use it this year to run the Marching Soldiers. The 4 LEDs in series will be replaced with a 555 timer circuit. This will feed a clock pulse to the output device every time the music strikes a loud beat. This I hope will achieve the effect of the Marching Soldiers beating their drums every time the music hits a beat.
