Connect relays to digital output pins on whatever Arduino via appropriate isolation circuitry, starting at some pin (default 5), sequentially Set the start pin and number of relays at the top of the ...

This project involves controlling a relay using a Light Dependent Resistor (LDR) and an Arduino. The system detects the ambient light intensity using the LDR sensor. Based on the detected light level, ...

After wiring up each outlet so it can be controlled independently, he set out designing a four port relay board. This was a pretty simple build – four 10 Amp relays and a few terminal blocks.

These microcontroller-based systems display IIoT and edge computing capabilities ideal for industrial automation. For example, the Arduino-based Portenta Machine Control PLC, with its array of digital ...
