i am trying to do a project
where i would like to controll the intensity of certain number of electric bulbs according to the music played.
i would like to make a system which consists of 32 bulbs
the out put of a music player will be connected to the system
when the music plays,the bulbs will glow according to the purticular sound frequency and also will change the intensity in accordance with the intensity of a purticular instrument.can anyone suggest an solution for this?
If you can't find the input transformer (8ohm to 5kohm) you simply can use a 12V stepdown transformer i.e. 220VAC to 12VAC, use the 12VAC winding for audio input (use a veriable resistor and a cap at input) and 220VAC winding for output.
These are very simple circuit, I give you an idea that you can filter out the audio and say 10 or more channel and use MOC (optocoupler) and Triac's, to switch to mains. If u want to use single channel and 32 bulbs, it depends on the SCR/Triac's ratings (use higher one), but if u mean 32 channels, yes you can from the above idea.
There is also a free plugin for Winamp called DiscoLitez. You can hook up to 32 Lights (or other effects) to your PC and it can control them based on sound, timers, or user input (like switches and sliders). You can check the software out before building circuits for it to see if it's what you want (kind of a poor mans DMX system). The URL is: **broken link removed**
Good Luck =)
