How to blink LED



  • Hi, I'm pretty new to MySensors and Arduino and I'm trying to write a simple code. I would like to toggle switch from Domoticz which will blink the LED (pin 13 on my Arduino Nano) and then Arduino will send the pin state back to Domoticz.
    My Arduino is serial connected with Raspberry Pi and Domoticz. On Domoticz I have a serial MySensors Gateway.
    Can u help me?
    Thank you in advance.

    Hi @piotr, welcome to the forum!

    You should be able to use the relay example

    BUT: pin 13 is used for spi communication with the radio, so you will need to use softspi instead. Doing that might be unnecessarily complicated, so it might be easier to connect a led and a resistor to some other pin instead.
