When you measure mains power with your own electronics for safety reasons you should use sensors that provide isolation between dangerous mains voltages and Arduino (commercial mains power measurement devices packed to well insulated case can be built without isolation).

### Phase Smart Energy Meter using Arduino - Engineer

)Step-down transformer(220V to 6V AC) but the arduino can't take AC voltage to read that also 6V. 2)Lets get the 6V down to 5V operating voltage of Arduino so that it can measure or read, so voltage divider using 2 1k resistor so it comes to 3V AC(approximately) 3) To get a DC we have used a diode as a half wave rectifier
