Hello,
I wish to make a circuit that can be used to control 3-5 lights in accordance with the rythm of some audio signal fed to it.
I have heard of some music ICs but doesnt know their part no. nor their function.
Please help..
Don't use that impossible to solder IC and drive it with a computer, use an LM3915 instead.
It has ordinary pins that mount through holes on a circuit board or on stripboard.
Its datasheet shows a peak detector circuit that holds the peak level for a moment long enogh to see it. It drives up to 10 LEDs and has built-in current regulation for the LEDs.
explorerbaba dosn't mention what size of lights.
I recall in the mid-late 60's we built simple color organs using scr's
very simple circuit. I recall powering 150w colored bulbs. One bulb per scr.
am sure if this is what you want then a search engine. As for dividing the frequencies into 3 sections then filters. The color organ had adjustable filters.
