As you may well know, Arduino’s analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V analog reference voltage) and this range can be increased by using two ...

Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool ... such as a voltage divider or an adjustable regulator, can give you a reference ...

Voltage and Current divider arrangements are the common in electronic circuits. Before selecting the value of resistors, it is necessary to calculate the voltage and current from the output of a ...
