Arduino Uno LED Bar Graph Display

This project demonstrates how to create a simple LED bar graph display using an Arduino Uno.

The number of LEDs illuminated represents a simulated sensor value, mapped to a visual bar graph on the LEDs.

Components Needed

Connect each LED's anode (long leg) to digital pins 2 through 11 on the Arduino Uno.

Connect each LED's cathode (short leg) to a current-limiting resistor (220Ω - 1kΩ).

Connect the other end of the resistors to GND.

Wire up the LEDs and resistors according to the circuit setup section.

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Uno.

Observe the LED bar graph display, which will simulate a sensor value incrementally.

Ensure LEDs are correctly oriented and connected to the appropriate digital pins on the Arduino Uno.

Adjust the code to map sensor values or other input data to the LED bar graph as per your project requirements.

Experiment with different resistor values to adjust LED brightness and current consumption.
