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 ...

This code is designed to measure analog voltage input from pin A0 and calculate the corresponding voltage value using an Arduino board. Here's a breakdown of the code: int voltageV = A0;: Declares a ...

The presented solution for measuring voltage of Zener diodes using Arduino is completely new and original. The circuit uses LM317 as a constant current source and the whole measurement process is ...

Voltage Devider For measuring the voltage with the arduino we need a voltage devider as the analog inputs only can handle 0-5V.

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 ...

The circuit was based on the use of Arduino AVR to build a high voltage programmer which can be used to fix pesky fuses. The circuit was based on the use of Arduino AVR to build a high voltage ...

Denis Hennessy recently encountered a problem we've all faced: he needed some AAs for a battery-eating gizmo, and he was overwhelmed by the choices available. Ignoring the shiny packaging and its ...
