    • Session 12 – Final Project: Mini Weather Station
    • Level 2 Quiz – Inventor Check
      10 xp

Students who completed Level 1 learn to read real-world sensors, clean up noisy data and show information on displays. They write cleaner code with functions and non-blocking timing, and finish by building their own mini weather station.

  • Ages 11–14
  • 12 sessions × 90 minutes + final quiz
  • Level: Intermediate

What students will learn

  • Connect and read digital and analog sensors, including libraries (DHT, IR, LCD)
  • Use variables, functions, arrays and millis() for multitasking
  • Debounce buttons and detect state changes
  • Design, build and document a multi-sensor project

Kit

Level 1 kit + HC-SR04 ultrasonic sensor, DHT11 temperature/humidity sensor, HC-SR501 PIR motion sensor, tilt switch, IR receiver (VS1838B) + remote, 16×2 LCD with I2C backpack.
