Voltage Measurement measure analog voltage input from pin A0 and calculate the corresponding voltage value using an Arduino board.

This project is a great example. [Scott Daniels] takes a look at the other voltage measurement options available to AVR chips used by Arduino.

Voltage Divider (Simple Voltage Monitoring): This is the simplest and most common method for monitoring battery voltage. Two resistors are used to scale down the voltage to a level that the Arduino ...

If you use the analog inputs of your favorite microcontrollers, sooner or later you have needed to check their linearity and accuracy over the entire range of input values. This precise and compact ...
