Kitchen Timer Lesson Key Concepts

Build a Kitchen Timer and explore how robotics, math, and programming work together in a hands-on way! This lesson blends logic, timing, and problem-solving using Thymio and VPL3:

• Use Thymio’s top LED counters to explore binary counting and represent numbers with lights.
• Create a kitchen timer in VPL3 that counts 5, 20, and 60 seconds.
• Test your timer with a stopwatch and observe how accurate your program is.
• Advanced: Use colors and counting patterns to track longer time intervals.
• Advanced: Build a multi-minute timer by combining counters and loops.

Lesson Overview

In this lesson, students will:

1. Learn how Thymio uses LED lights to count in binary.
2. Create a VPL3 program to run a timer for different time intervals.
3. Test and compare timer accuracy using real-world measurements.
4. Extend the program to count longer durations using patterns and logic.

By the end of this lesson, students will understand how counting systems and programming can be used to measure time.

Important Notes:

Timer accuracy depends on how the program is built and tested. Small timing differences can add up, so use a stopwatch to check and adjust your results.

Tips for this Lesson:

1. Start with small time intervals before building longer timers.
2. Use clear LED patterns to track counting progress.
3. Test multiple times and adjust your program for better accuracy.
4. Break longer timers into smaller steps to make them easier to manage.

FUN FACT!

Did you know that computers use binary code to keep track of time and perform calculations? Even simple timers rely on counting systems similar to the one you are building with Thymio!
