Introduction: Blinking Into DIY Electronics With Arduino

By

For hardware enthusiasts, Arduino Blink is essentially a digital "Hello World!" The onboard LED needs to be programmed to blink on and off at a predetermined interval using an Arduino microcontroller. The foundation for understanding programming, circuit design, and hardware interaction is laid by this easy project.



Supplies

To embark on your Arduino Blink journey, you'll need the following:

1) Arduino Board

2) USB cable for connecting Arduino to computer

3) Arduino IDE

4) LED

5) Resistor

6) Breadboard

Step 1: Connect LED to Arduino

Connect LED with Arduino Board as shown in circuit



Step 2: Connect Arduino Board With PC

Step 3: Upload Code

void setup() {

 // initialize digital pin LED_BUILTIN as an output.

 pinMode(LED_BUILTIN, OUTPUT);

}


void loop() {

 // turn the LED on (HIGH is the voltage level)

 digitalWrite(LED_BUILTIN, HIGH);

 // wait for a second

 delay(1000);

 // turn the LED off by making the voltage LOW

 digitalWrite(LED_BUILTIN, LOW);

 // wait for a second

 delay(1000);

}


Step 4: See the Blinking LED

Once uploaded, the Arduino board will start running the Blink sketch.

The LED connected to pin will blink on and off at a default rate.

Step 5: Customize Blink Rate

In the Blink code, you can modify the delay values to change the on and off durations, customizing the blink rate.
