LED Bar Graph Pulsating Project

This project involves creating a 10-LED bar graph that pulsates light using a Raspberry Pi 4 and Python code. The LED bar graph will have 10 bars, each controlled by a GPIO pin on the Raspberry Pi.

Required Materials

To complete this project, you will need the following materials:

  • Raspberry Pi 4
  • Breadboard
  • 10 LEDs
  • 10 220-ohm resistors
  • Jumper wires

Circuit Diagram

The circuit diagram for this project is shown below:

In this diagram, each LED is connected to a GPIO pin on the Raspberry Pi through a 220-ohm resistor. The GPIO pins used for each LED are as follows:

  • LED 1: GPIO 21
  • LED 2: GPIO 20
  • LED 3: GPIO 16
  • LED 4: GPIO 12
  • LED 5: GPIO 7
  • LED 6: GPIO 8
  • LED 7: GPIO 25
  • LED 8: GPIO 24
  • LED 9: GPIO 23
  • LED 10: GPIO 18

Python Code

The Python code for this project is shown below:
