Hi everyone,
I'm having a problem. I've built a thermostater in order to operate an old fridge. I programmed Arduino for give me some information through Serial Communication via USB and Serial Monitor. Everything work perfect, except when the fridge's motor starts working. I think that the power variation may be confussing Arduino. I have to tell that is the board has a switching regulated power supply at 12 V 2 A.
¿How can I do? I don't want to lose connection with arduino...
