LED Music Sync Lamp!

Step 6Test and make sure it is working

Test on a breadboard with 1 led to fix brightness, tuning and resistance issues

voltage regulator also works in series ( previous version managed to work in parallel but thats because it didnt do anything..lol)

how to connect to an amplifier?? wut if i connect it to a speaker?

Mar 18, 2008. 8:10 AMoptimized4perfection (author) says:

the amplifier is so that the light brightness does not get controlled by the volume level. im using the audio signal from my computer at max vol (can go directly to speaker) but my speaker has its own built in amp so it doesnt change the brightness along with it

yes, just watch out how loud u have it, mostly just the bass, or u'll blow the LED, trust me, did it with a sub, just use a resistor
