The Relay Shield provides a solution for controlling high current devices that cannot be controlled by the Arduino’s Digital I/O pins due to their current and voltage limits. The Relay Shield features ...

This schematic is reverse engineered from the MOVI Arduino Shield without the assistance of X-ray or destructive tear-down. It is likely incomplete and inaccurate. There is no PCB layout included.

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100. Hello, I'm going to share again with another project that helps many of you to solve ...

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 ...
