Four Channel Arduino LCD Voltmeter

Four Channel Arduino LCD Voltmeter: "Analog channels A2 to A5 on an Arduino Uno are used to measure four different voltages. The measured voltages are displayed on a 16 character by 2 line LCD.

The four channel Arduino multimeter can measure four independent DC voltages that can each be in the range of 0 to 50V.

Voltages are displayed with one decimal place, e.g. 5.3V, 12.8V, etc.



This video shows the Arduino voltmeter being used to measure the voltage of four batteries. Each battery has a different voltage.
