RGB LED Lamp Driver Board

at 10:21 pm. Filed under Electronic Hacks


With this RGB LED Lamp Driver Board circuit you can make an ordinary light a bit more interesting. With the press of a button you can change the light to whatever color you like. An AVR microcontroller is being used to PWM the RGB LEDs.

Video after the jump.

“The lamp uses a single momentary button to switch (you need special drill bits to drill the hole in this thin plastic, trust me, check Harbor Freight for them!) between the colors and the two color mixing modes (one, I jokingly refer to as “light switch rave” and the other a slow color changing mode). My wife absolutely hates the blue hue of normal LEDs, so I knew my design would have to incorporate a few warm white LEDs in addition to the RGB LEDs, thus the 3 warm white LEDs in the middle of the board.”
