Help making synch-with-music lights?
Hi, I have a strip of LED's and want to connect them so they synch with music (just so they flash to the sound not some fancy microcontroller stuff) and I was wondering how would I connect them because if I try to just connect them to my amp they dont come on as it's not powerfull enough, I read you can use a transistor in this case but I thought that transistors just switched on and off and not varied with the volume. If I should use a transistor could someone suggest one for me (preferably out of Maplins.co.uk). The whole strip uses 12V. I also noticed that it works ever so slightly when you unplug the speaker and have just the LED's plugged in - is there any way to get around this?
