Single Colour LED strip brightness controller

Former Member

I have been working with a single colour LED strip with voltage requirements of 12V. I want to control the brightness of the strip according to sound signal. The LED strip has only power and ground signal, so I am able to deduce how to communicate the signal to the LED strip and control its brightness accordingly.

 

Thanking you in advance

    Slightly off forum topic, but look at PWM modulation. Thats the only

    reliable way to dim multiple parallel LED's while keeping uniformity. You

    will find chips made for this. Or you can go for digital led strips (take a

    look at WS2812), where brightness and color is individually controlled

    digitally.
