The relay on the 5V Relay Module should now switch on and off at 1-second intervals, controlling the high-voltage device connected to the relay's output terminals.

Verify and upload the code to your Arduino board.

PinMode(RELAY_PIN, OUTPUT) // Set the 5V Relay Module pin as outputĭigitalWrite(RELAY_PIN, HIGH) // Turn on the relayĭigitalWrite(RELAY_PIN, LOW) // Turn off the relay #define RELAY_PIN 7 // Pin number to which the 5V Relay Module input is connected

Copy and paste the following code into the sketch:.Open the Arduino IDE software on your computer and create a new sketch.Step 4: Control the 5V Relay Module with Arduino: Connect the IN pin of the 5V Relay Module to any digital pin on the Arduino board, such as D7, using a jumper wire.Connect the GND pin of the 5V Relay Module to the GND pin on the Arduino board using a jumper wire.Connect the VCC pin of the 5V Relay Module to the 5V pin on the Arduino board using a jumper wire.Insert the 5V Relay Module into the breadboard so that its pins are on separate rows.Step 3: Connect the 5V Relay Module to the Breadboard: The IN pin is used to provide a control signal from the Arduino to activate or deactivate the relay.The GND pin is connected to the ground of the Arduino.The VCC pin is used to provide power to the relay module (typically 5V).It typically has three pins: VCC (power supply), GND (ground), and IN (input control signal).The 5V Relay Module is an electromechanical switch module that can be used to control high-voltage devices with a low-voltage microcontroller, such as an Arduino.
