    • Constant current high voltage dimmable led driver

      Hello everyone,

      I've been playing with MySensors mainly with relays, bounce door sensors and rgb led 12v driver.

      Today I would like to "MySensorize" a dimmable dual channel ceiling light I've just received.

      Here are some pics of these 2.4 Ghz led driver, providing 240mA@130-185V

      The receiver is on the yellow PCB and my goal is to find how to replace this specific part with an arduino.
      I've found it receives 5V DC

      The 2 channels correspond to 1 warm and 1 cold led strips.
      If I can find how to PWM the green board with your help, I will then work on code for piloting it with a dual monostable button (one for on-off-dimming long press and the other for switching between warm/cold/natural)

      The ceiling lights itself is this one

      it has a lot of spare splace so it's easy to include the arduino.

      Hope someone has ideas of how to PWM it.

      Thanks
