Question 9: Protocol Selection

You're designing a robot that needs to connect a temperature sensor, an accelerometer, an LCD display, and an SD card module. Explain which communication protocol (I2C, SPI, or analog) you would choose for each component and why.

Question 10: Multi-Sensor System Design

Describe how you would implement a sensor fusion algorithm that combines data from an ultrasonic sensor, a gyroscope, and a camera to help a robot navigate through a maze. What would each sensor contribute, and how would you handle conflicting information?
