Switch HDMI on/off by pressing button connected to GPIO.

  • Hi all,

    I know this might not be the hardest thing to program, but im kind of a noob and it took me a day and I could not get it running. I got all the other parts off the mirror working but the final part will be that i can only turn the screen on and off by pressing a button. I know this can easily be done by MMM-button module. But im clueless on what to do next.


  • install the MMM-Admin module. It will serve up a webpage and you can control the HDMI from there…even use it on your phone. works well
