Of course, one could almost accomplish this by just using an Arduino Due, which has a 12-bit A/D converter (almost, because it has a lower reference voltage of 3.3 V). But that wouldn’t be as ...

So [Faransky] uses a X9C104P 100KOhm 8-bit digital potentiometer as a voltage divider on ... with a DC-DC boost converter to get 5V for the Arduino. Though if you wanted to create a benchtop ...

Aside from the USB port, you can power your Arduino boards with any regular battery connected to its VIN pin. The supply voltage depends ... Analog-to-Digital (ADC) converter, so all of its ...
