LED Programming

Learn programming fundamentals through colorful, visual feedback. LEDs provide immediate visual confirmation of your code, making them perfect for learning control structures and user interaction.

Learning Objectives

By the end of this unit, you will be able to:

  • Control LED colors programmatically
  • Create animations and visual effects
  • Handle user input with buttons
  • Apply programming concepts to visual output

Unit Structure

This unit is designed as a 4-day progression:

Day 1: Color Control - Learn RGB color theory and basic LED programming

Day 2: Animation - Create moving patterns and visual effects
