LED Dimmer with Arduino Nano

This simple project demonstrates how to use an Arduino Nano to blink an LED on and off at one-second intervals. This project is a fundamental exercise to familiarize yourself with basic Arduino programming and circuit building.

Components Needed

Circuit Diagram

Circuit Setup

1.Arduino Nano to LED:

Connect the anode (long leg) of the LED to digital pin 13 on the Arduino Nano through a 220Ω resistor.

Connect the cathode (short leg) of the LED to the GND pin on the Arduino Nano.

Instructions

1.Circuit Setup:

Connect the LED and resistor to the Arduino Nano as described above and shown in the circuit diagram.

2.Code Upload:

Connect your Arduino Nano to your computer using a USB cable.

Open the Arduino IDE and paste the provided code.

Select the appropriate board (Arduino Nano) and port from the Tools menu.

Upload the code to the Arduino Nano.

3.Testing:

Once the code is uploaded, observe the LED blinking on and off at one-second intervals.

Applications

Indicator Lights: Use blinking LEDs as indicators for various states in projects.

Learning Tool: This project is perfect for beginners to understand basic Arduino programming and circuit building.

Notes

Ensure correct orientation and connection of the LED and resistor to prevent damage.

Experiment with different delay values to change the blinking frequency of the LED.
