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 ...

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 ...

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 ...

With a simple Pro Mini board and a few other components, projects that 20 or 30 years ago were unthinkable (or would have cost a small fortune) are realized easily and affordably in this book: From ...

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 ...

If you frequently use a 3D printer for your projects then you may experience issues calculating the material weight and length usage. If so, then you might be interested in this project using Arduino.
