The folks over at Adafruit have been busy designing an LED matrix wristwatch for a while now. The circuit works great, but since this watch is powered by a coin cell battery, they’d really like to get ...

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

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 ...

Makers and developers that are looking to carry out or create projects for environmental monitoring may be interested to know that the Arduino compatible EnviroDIY Mayfly Data logger board is now ...

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 ...

Those of you that are looking for a temperature datalogger may be interested in a new piece of kit which has arrived at the Adafruit website this week in the form of the Pax Instruments T400 ...
