I am using this model. Should take 20ma.
Quote:This confuses me, there is any mistake here?
What I mean is: if I apply a multimeter I see the voltage supplied to the led shifting consistent with on-off blinking behavior. Voltage when powered from USB ALONE is OK, something like 2,65 volts. When Powered from 12v I see around 6v.
Quote:Could you please just check, what voltage you have in the output pin of the 7809 when the board is powered by 12V?
9 Volts.
Quote:You are measuring this between the two fan pins, or between the +9V fan pin and GND?Between the two fan pins.
No temperature sensor connected. Settings modified like this:
byte fanOn_HiTemp = 1000; // RS Fan turn on when outside temperature is >= than this value (ºC)
byte fanOn_LowTemp = 0; // RS Fan turn on when outside temperature is <= than this value (ºC)
byte fanOn_LowWind = 99; // RS Fan turn on when Wind Average is <= than this value (m/s)
