5. Shake Activated LED - RoboticSchools

Your LED turns ON when you shake the Microbit. Which sensor is detecting the shake gesture? 📳

• Light Sensor 💡

• Temperature Sensor 🌡️

• Accelerometer 📳

• Sound Sensor 🔊

Which of these is NOT a valid gesture detected by the Microbit's accelerometer? 👀

• Shake 🌀

• Swipe 👋🏻

• Freefall 🪂

• Tilt left ↩️

What happens if you accidentally connect the LED to P2 but your code writes to P0? 🤔💡

• The LED will not turn ON ❌💡

• The Microbit will show an error ⚠️

• Nothing will happen on shake 🤷‍♂️

• The LED will blink continuously 🔁💡

🎮 You want to turn ON the LED by shaking and turn it OFF by pressing the Microbit logo. Which code blocks will do the job? 🤔💡
