WebIn this tutorial, we will test out the four relays on board the Arduino 4 Relays Shield. This shield is a great addon for the Arduino UNO board, as it has four relays capable of handling loads up to 48V. To control the relays, we need to use the following pins: Relay 1 - pin 4. Relay 2 - pin 7. Relay 3 - pin 8. Relay 4 - pin 12. WebUpload the sketch "4 Channel Relay Demo " to the Arduino Uno or ATMega2560 board. Then you can see the LED cycle between on and off. The actual figure is shown below: Arduino Sketch: 4 Channel Relay Demo /***** Name:4 channel_relay Description: control the 4 channel relay module to ON or OFF Website: www.handsontec.com Email: techsupport ...
