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 ...

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 or ...

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 ...

All power supplies have a current measuring system designed for a specific application. This limits the voltage range for which the current can be measured. The ZXCT1009 and ZXCT1010 can take care of ...

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 ...

Battery cell open circuit voltage (OCV) is an important measurement made on the cell during manufacturing to determine cell performance quickly and reliably. Download our application note to learn why ...
