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 ...

An Arduino nano and relay module with 4 relays (see picture above) was used to simulate and replace the guitar 3-step switch. The project for Arduino is in PlatformIoClamp15. Node-red was used to ...

Digital pins D3 and D4 of Arduino Board2 are interfaced to relay module (RM1) to switch the appliances on/off. If on pressing switch S1 relay 1 in RM1 gets energised, it means the electrical appliance ...

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 ...

I checked several Arduino projects and related libraries available online but was confused. Finally, I decided to do my first test with the help of a Windows 10 computer as the host. First, I ...

Electronic, Arduino enthusiasts and makers looking for a project to keep them busy this weekend, may be interested in a cool custom switch created by Dave ...

The Arduino connects to the FM radio module over I2C. ... The AM-FM selector knob was fitted with a micro-switch connected to the Arduino for selecting the preset stations.
