This project demonstrates how to interface a relay module with an Arduino to control high-voltage appliances safely. The setup involves using a relay as a switch, allowing the Arduino to control ...

This device enables generic loads (here: valve actuators) to be controlled by TCP/IP. The power for the relay card and the Arduino Pro MINI is derived by a POE 802.3af ethernet switch. A Texas ...

[Reza’s] methodical investigation of this remote controlled outlet let him patch in with an Arduino using a 433 MHz transmitter. This is a single-device unit, but the techniques used here should ...

Finally, your Arduino toolkit will be incomplete if you ... it’s a good idea to grab a couple of motors and relay modules for your tiny microcontroller. Really, the sky’s the limit when ...

An Arduino Pro Mini provides the brains for the charger, and the source code and all the needed information to build your own like charger is on GitHub. What’s outstanding about the guide though ...

Seeed Studio’s XIAO 6-Channel Wi-Fi 5V DC Relay is a compact ESP32-C6 Wi-Fi relay board built ... On top of that, you have the option of using Arduino IDE, ESP-IDF, or MicroPython for custom ...
