Hello everyone, :o
I am making a small home automation project which consists of a nano based setup which monitors room usign pir sensor for motion and turns off light fan once it detects people are not there in the room.
So anyways the issue is pretty isolated. I have 2 relays - 2 channel 5v low relay. When I test then with my uno separately connecting it to uno 5v supply I get both channel relays getting power. (In1 and in2) but when i connect it my nano which already has other stuff loaded on it... I get only one channel getting power... Mind that one single connection powers both channels on these relays.
My relay is exactly this one
Could it be a power inadequacy ?
