Arduino C++

  Here's a basic tutorial for blinking an LED with Arduino C++:

1. Hardware Required: Arduino board, LED, 220-ohm resistor, breadboard, and jumper wires.

2. Circuit: Connect the longer leg of the LED (anode) to a digital pin on the Arduino through a 220-ohm resistor. Connect the shorter leg (cathode) to the GND pin.

Code:
int LED_PIN = 13; // Use pin 13 (or any other digital pin)

void setup() {

  pinMode(LED_PIN, OUTPUT); // Initialize the LED pin as an output

}

void loop() {

  digitalWrite(LED_PIN, HIGH); // Turn the LED on

  delay(1000);              // Wait for 1 second (1000 milliseconds)

  digitalWrite(LED_PIN, LOW);  // Turn the LED off

  delay(1000);              // Wait for 1 second

}

3. 
   

   • pinMode(LED_PIN, OUTPUT): Configures the specified pin as an output.

   • digitalWrite(LED_PIN, HIGH): Sets the pin to HIGH (5V), turning the LED on.

   • digitalWrite(LED_PIN, LOW): Sets the pin to LOW (0V), turning the LED off.

   • delay(1000): Pauses the program for 1000 milliseconds (1 second).

4. Upload and Run: Upload the code to your Arduino. The LED should blink on and off every second.

You can adjust the delay() values to change the blinking speed.
