LED Driver Exercise

This exercise demonstrates C++ object-oriented programming by implementing a multi-colored LED driver.

Hardware Setup

ESP32 Pinout Diagram LED Breadboard Pic

Connect an RGB LED (common anode) to your ESP32:

  • Red: GPIO 27
  • Green: GPIO 26
  • Blue: GPIO 25
  • Common Anode: 3.3V (through a 100Ω resistor)

What You'll Implement

Part 1: Complete the MultiColorLed class

Open src/led.cpp and implement the TODO sections:

  • Constructor initialization
  • on(), off(), toggle() methods
  • set_color(red, green, blue) method

Part 2: Test your implementation

The main program in src/main.cpp cycles through different colors to test your LED driver.
