A digital voltmeter with microcontroller is designed. Digital voltmeter with pic can read voltage of 0-40 volts. This voltmeter can only read DC voltage. The digital AC voltmeter can also be designed using microcontrollers. The digital DC voltmeter is designed to measure the DC voltage using the PIC16F877A microcontroller. The voltage divider circuit is used to divide the voltage into two parts. To prevent more than 5 volts from appearing through the pic microcontroller Because the microcontroller can not read the voltage more than 5 volts directly. The LCD screen is interconnected with the microcontroller to display the measured voltage value. The built-in analog micro-controller of pic microcontroller is used to measure analog voltage.
