Please log in for more thread options What device (component) would I need to use if I wanted say blue lights to come on when a 400 - 500 cycle tone was played. I would like to build a display light with 5 or 6 different color lights, say like Christmas Lights, and each color comes on and off depending on the freq. of the sound and the duration . Any help? | ||||||||||||||||||||||||||||

Hello Ronnie, Here is a schematic I saved from this group a few months ago. http://www.oldtemecula.com/theremin/images/led_color_organ.gif You could replace the colored LED's with opto-isolators to drive incandescent bulbs at a 120 volts ac. http://en.wikipedia.org/wiki/Opto-isolator Good Luck, * * * Christopher Temecula CA.USA http://www.oldtemecula.com | ||||||||||||||||||||||||||||
