[quote=“Stiansen, post:39, topic:193803”]Thank you thank you!!
Got it working last night and I have to embarrassingly admit that it was set to Russian frequency… I opened a new window in Arduino IDE when I uploaded the second sketch, then it probably changed to Russian by default. But thank you again for the support!
Now got it up and running with 4 channels and temp&humidity. Pretty great.
However, I got one small problem. I have not got my 4 channel relay yet (plan is to control the ventilation system), but do you guys know why my outputs are inverted? I have connected diodes but when I set the digital output high the diode turns off, and on when I turn the output low. Also need to pulse the output signal since I just want it to send a control signal to turn on different settings.[/quote]
Great that you found the error. How are your diodes connected? Could you post a sketch/photo?
