Creating pulse effect for LED car ground kit
I'm working on adding some visuals to my car, among them a LED ground effects kit. It uses 12v LED strings from BestHongKong.com powered by the car's aux power. I want to get it to pulse, fading in and out about once a second. I tried a 555 timer and a capacitor bank in parallel with the light array, but it doesn't show any difference (I'm guessing RC is too small to be even noticeable, so I might just need a larger bank). Anyone else have experience with this?
