Connecting 3W Power LED with Surilli GSM

In this tutorial, we will interface 3W Power LED with Surilli GSM. By connecting the signal pin of 3W Power LED to Surilli GSM pin 5, the 3W Power LED will start blinking ON and OFF after some period of delay, and will give off an illuminating light.

What Is a 3W Power LED Module?

The 3W Power LED Module is a very bright LED that works on either 3.3 or 5 volts. It is bright enough to be used for illumination.

Hardware Required:

• Surilli GSM

• Connecting wires

• 3W Power LED Module

• Breadboard

Connections Between 3W Power LED Module and Surilli GSM:

• G (3W Power LED Module) ---> GND (Surilli GSM)

• + (3W Power LED Module) ---> USB (Surilli GSM)

• S (3W Power LED Module) ---> PIN 5 (Surilli GSM)

STEP 1: Set Up Arduino IDE for Surilli

Make sure you have selected the right port, board and processor for the Surilli as shown in the picture below and it is programmable (compile and upload “Blink” from File>Examples>Digital>Blink onto your Surilli to check if everything is working fine).

STEP 2: The Circuitry

The circuitry is very simple. It's mostly the programming. Follow the figure below to set up your hardware.

STEP 3: Upload and Burn Code Onto Surilli

Now you have completed setting up your hardware and Arduino IDE. Copy and paste the Arduino sketch given below into your Arduino IDE and hit upload.After it is uploaded, the LED will start blinking ON and OFF after a few periods delay and will give off an illuminating light.

Arduino Code

void setup() {
 pinMode(5, OUTPUT);
}
void loop() {
 digitalWrite(5, HIGH);   
 delay(1000);              
 digitalWrite(5, LOW);    
 delay(1000);              
}

Play with the program to see how it reacts to different values and logic.
