  • It's just a metal disk (a 5p coin in this case) which makes a connection between the 2 electrodes above each led, this is detected by the microcontroller and it turns on or off the corresponding led.

  • hi, what's the significance of the thing that you are holding?

    looks like a great project! I want to cover my floor in that hehe
