DC Voltmeter using Arduino and Seven Segment Display. This time we will be interfacing Arduino with 7 segment display and MA7219 IC to measure voltage ranging from 0-50V with almost no error at all. This DC voltmeter is linear with voltage and shows a linear characteristics from 0.01 Volt to 50 Volt.

0-50V DC Voltmeter using Arduino and Seven Segement Display

Introduction: We are back again here with the latest Arduino Project, i.e DC Voltmeter using Arduino and Seven Segment Display. This time we will be interfacing Arduino with 7 segment display and... Read more »
