Part 3: I2C

~60-75 min

Welcome back from lunch. In this module, you'll move beyond GPIO to a communication protocol — I2C. More importantly, you'll experience the embedded-hal abstraction in action by using a driver crate that works across any microcontroller.

What You'll Do

1. Bus scan — discover what I2C devices are connected to your uFerris board
2. Driver crate — use a third-party driver to read real sensor data
3. Adaptation challenge — explore a second sensor or different driver configuration
