 Bigger Bigger Smaller Smaller Reset Reset
Im trying to use a sound sensor and a LED strip together. I've been able to get them both working separately, but not together. I can even get a single LED to work with the sound sensor but when i replace the single LED with the LED strip, it doesnt work. I feel like it may be a voltage issue?

I can hook up the LED strip to 5v and ground and get it to work, the problem is that the + cable for the strip has to be on a digital pin and not straight to 5v. Any help would rock!

The LED strip you have there probably needs 12V DC and it draws a lot of current, in range of 3A for 5meter long strip. So Arduino port is not going to cut it, you need some better design . . .
