I'm trying to control an RGB LED strip with PWM, but I'm having a lot of trouble. My setup is a Parallax Propeller microcontroller connected to some transistors and MOSFETS that allow it to switch 12v on and off to each color channel of the LED strip. My problem is that even with the PWM set to 60 Hz, 1% duty cycle, the lights are still quite bright. This prevents me from mixing the colors like I want to. Could it be that my LEDs have a maximum switching frequency? Or is it more likely to be a problem with transistor circuit? If anyone has any ideas I'd love to hear them.
