                 By Engr.Habib Ur Rehman

Components/Equipment Required:

            Following Components/Equipment are required to perform task.

1.    Arduino Uno (https://piees.pk/product/arduino-uno-r3/)

2.    Single Channel Relay Module (https://piees.pk/?s=relay&post_type=product)

3.    Buzzer/LED Light (https://piees.pk/product/passive-buzzer-module/) & (https://piees.pk/product-category/lcds-display/)

4.    Breadboard

5.    Jumper Wires (https://piees.pk/product-category/jumper-wires/)

Circuit Diagram:

Note: If you connect with “Normally Open” then output will be first “High” then it will be “Low” and If you connect with “Normally Close” then output will be first “Low” then it will be “High”

Arduino Program:

int relay = 10;

void setup ()

{

  pinMode (relay, OUTPUT);

}

void loop ()

{

  digitalWrite (relay, HIGH);

  delay (1000);

  digitalWrite (relay, LOW);

  delay (1000);

}
