The only thing that seems to work fine is when, I disconnect the 220vAC mains from the relay contacts, but that defeats the purpose :-),
I am confident that the relay is not making any disturbances to the lcd but the 220v AC mains when connected to the relay even without any load, garbles the lcd.
I mean the lcd only, not the arduino.
hi, as I have stated before, if the relay module alone connected to the arduino without the 220v ac mains connected to it , works fine ant not creating lcd garbling. when I connect the 220v ac mains even without the load (solenoid valve) connected to it, garbles the lcd,
this problem is not yet solved,
Iam awaiting for the forum help... :*
