Sensor Fusion

If you close your eyes, you still know which way is up. Robots use 'Sensor Fusion' to do the exact same thing!... ✨ PAN'S RULE: If it's not chaotic, it's not magic! ✨

Combine data from accelerometers, gyroscopes, and distance sensors to understand the physical world.

⚠️ SAFETY DIRECTIVE: We only work with safe 5V USB power or AA/AAA batteries. NEVER plug homemade electronics into a wall outlet or mess with mains electricity. Keep the magic safely low-voltage!

Digital Protocols

You only have a few pins on a microcontroller. How do you plug in 5 different temperature and gyroscope sensors? You use the I2C (Inter-Integrated Circuit) protocol, which strings them all together on just two wires, like houses on the same street!

📺 How To Mechatronics — "How I2C Communication Works" — The master-slave architecture that powers digital sensors.

⚡ Protocol Exam

If you have three different sensors connected to the same I2C wires, how does the master brain know which sensor it's talking to?

Each sensor has a unique digital Address (like a house number).

You must unplug the unused sensors physically.

🧠 Concept Checkpoint

Are you ready to apply what you've learned in this module to build something awesome?

Yes, I'm ready to build!

I need a minute to review.
