Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal … ...

In National 5 Physics examine the current and voltage in series and parallel circuits to formulate rules and determine unknown values.

These variable resistors allow the output voltage to change in response to environmental conditions, such as light or temperature. This makes potential dividers versatile for various applications.

Dropping the voltage divider and measuring the current through a current mirror generates a linear voltage across its output load resistor that can be easily read by your microprocessor.
