Lumen connections and control with raspberry pi

Hi @lbentes,

The Lumens can be controlled by either a PWM signal (1100-1900us) or turned on by connecting the signal wire directly to DC power, so yes this is possible :slight_smile:

If you just want to turn them on/off you can use one of the GPIO pins set up as a digital output, and set it high when you want the lights on and low when you want the lights off. If you want brightness control you’ll need to use a library that can output a PWM signal and connect the Lumen signal wire (yellow) to one of the compatible PWM pins for the library you choose. I discuss a couple of different Raspberry Pi python libraries that support PWM in this post.

Feel free to ask any follow-ups if something isn’t clear :slight_smile:
