Single-channel Relay Motor control – Arduino

In this tutorial, we will learn how to control a single-channel 5v relay module with Arduino.

NOTE: Please note that relay mounted on this board is 5v, not 12v relay.

Item Required:

1. Single-channel 5v relay board – 1Nos.
2. Arduino UNO – 1 Nos.
3. Hobby DC Motor – 1 Nos.
4. USB Cable A to B type – 1 Nos.
5. Jumper Wire M/M
6. Jumper Wire M/F

Connections:

Code:

int relay = 7;

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(relay, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(relay, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(2000);                       // wait for a second
  digitalWrite(relay, LOW);    // turn the LED off by making the voltage LOW
  delay(2000);                       // wait for a second
}
