i am trying to measure 220 volt using the resistor divider network. with respect to the measured input voltages i am switching AC load from relay but the problem is that after random number of switching the micro-controller is reset. please help any suggestion what i am doing wrong or any alternative approach .also there is no watchdog timer enabled
