Notes

L1 can be any 10-100 Watt lamp.R1 adjusts sensitivity. The greater the resistance, the less sensitive the colour organ becomes.Since this project is powered by 120 VAC, it must be installed in a case.You can also use the Teccor S2003LS1 SCR for SCR1. These give better sensitivity and brightness than the C106Y units.
