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 ...

Engineers and developers looking for a programmable logic controller (PLC) might be worth checking out the new CANADUINO Arduino MEGA 2560 compatible ... and 20 Outputs (8 x relay 250V/5A, 2 ...

The Arduino Team presented some new products at Maker Faire this weekend. It’s a significant update. The Arduino UNO and Arduino Mega 2560 update ... transistor, relay, power MOSFET, push ...

[JonBush] recently did a beautiful build of an Arduino-based fireworks controller ... [Jon] used a mega 2560 because he wanted to do the I/O directly from the device. His code only takes about ...

But what happens if we want to control time? We can answer this question with the bare motor rotation, and a more complex software. For this project I am using the Arduino Mega 2560. First, we should ...

Meanwhile, the Arduino Mega is getting the same USB chip along with an ATMega2560 processor with twice the memory. Right now only 128K is available, but that's a software limitation and they're ...
