We think it’s a great learning experience to tear back the veil of abstraction and learn a bit more about the hardware found on an Arduino board. This project is a great example. [Scott Daniels] takes ...

In analog and mixed-signal circuits, the voltage reference acts as the standard against which other signals are measured. Inaccuracy and variation in the voltage reference directly impact the accuracy ...

Voltage references are available with fixed and adjustable reference voltage outputs. Adjustable output is set by a resistor divider connected to a reference pin. These references are either shunt ...
