Programming Arduino isn’t as hard as you think! Today, we’ll start with the Blink project, which is like the “Hello World” of the Embedded System world.

Required Equipment

1. Arduino Uno R3 Board
2. USB Cable
3. Computer with Arduino IDE installed

Coding Steps

1. Open Arduino IDE
2. Type the following code:

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // Turn on LED
  delay(1000);                       // Wait 1 second
  digitalWrite(LED_BUILTIN, LOW);    // Turn off LED
  delay(1000);                       // Wait 1 second
}

3. Press the Upload button and see the result on your board!

Easy, right? Just like that, you’ve stepped into the world of IoT. If you want to do more complex projects, feel free to consult us!
