Blink LED Code for Arduino

This code is an Arduino sketch that blinks an LED connected to pin 2 with a 1-second interval (500ms ON, 500ms OFF).

How It Works

1. The
   setup()
   function initializes pin 2 as an output.
2. The
   loop()
   function repeatedly:
   • Turns the LED on.
   • Waits for 500 milliseconds.
   • Turns the LED off.
   • Waits for another 500 milliseconds.

Usage

1. Connect an LED to pin 2 of your Arduino board:
   • The longer leg (anode) of the LED should be connected to pin 2 through a resistor (220Ω or 330Ω).
   • The shorter leg (cathode) should be connected to the ground (GND).
2. Upload this code to your Arduino using the Arduino IDE.
3. Observe the LED blinking on and off.

• BlinkLED.ino: The Arduino sketch file.
• README.md: This documentation file.

Notes

• Ensure that the resistor is used to limit the current and protect the LED from damage.
• You can change the pin number or delay values as needed.
