RetroBrewPi w/ Arduino Uno: Modify Script to turn-on LED


#1

Hey y’all hope all is well. I have a simple (not so simple?) question. I would like my BrewPi by way of the UNO to engage an LED every time either the heater or condenser is engaged. So, for instance, when the condenser is engaged a Blue LED is triggered.

I believe this to be a software solution but i don’t know enough about programming to look at the code and figure it out myself with potentially doing damage.

Thank you!

If you can live with a separate LED per device you could just put one in parallel with the low voltage side of each SSR (BrewPi output).

I went with this solution. Thank you!
