So, what do you do when your Arduino project needs to operate in a remote area or as a portable device? There are LiPo battery shields available, and although they may work well, recharging requires ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

The Arduino open-source development board is an immensely popular platform for engineers and makers to prototype their projects quickly. Its success and versatility is driven by its community, who has ...

Making an Arduino shield can be simpler than you think. This time I designed one to program Attiny and Atmega microcontrollers, that way I don't have to use a breadboard and make the wiring to program ...

OMC has launched a fibre optic transceiver shield for Arduino Uno, designed to work with PMMA (polymer) optical cables up to 25m long, plus demonstration software ...
