LinkIt ONE Tutorial - Hello World

What We're Doing

In the previous section we've got an insight about how to control an LED with electronic components but lets do some gimmicks with software for automatic control of the LED. You just have to upload the code that is available in this section. The code written initially switches ON the LED, after a delay of 3sec it switches it OFF. Let's start using the LinkIt board.

Things you need




Please click on the button below to download the code for the kit:

You can unzip the file to the Examples folder of your Arduino IDE.

To access the demo code open:

File -> Examples -> Starter Kit for LinkIt -> Basic -> L2_Control_LED

const int pinLED = 3;                      // LED connect to D13
void setup()
    pinMode(pinLED, OUTPUT);                // set direction of D13-OUTPUT
void loop()
    digitalWrite(pinLED, HIGH);             // LED on
    digitalWrite(pinLED, LOW);              // LED off


Making it better

In the previous section we used a capacitor to grow the brightness of the LED slowly and fade its luminosity slowly. Lets do the same thing without the capacitor but by purely changing the code.

To open the demo code:

File -> Examples -> Starter Kit for LinkIt -> Extend_Lesson –> L2_Breath_LED

More ideas

How do you change the frequency of the LED by modifying the code?
