Hello,
I am new to microcontrollers and am making a project to read ac mains voltage using pic microcontroller (pic 16f72).
But I am unable to find the circuit to step down the ac voltage to DC and that too to the max. level of 5 volts and what will be the ratio of input ac and the input to the ADC of the pic ,for the calculation in pic code for display purpose.
Can anybody help me with this .....
