Raspberry Pi and Arduino - Go to The Next Level - Activity 02 - Solution

This tutorial explains how to set up an Arduino to send random temperature data to a Raspberry Pi, which then controls an LED based on the received temperature. The Arduino generates a random temperature every second and sends it via serial communication. The Raspberry Pi reads this data, processes it, and sends commands back to the Arduino to turn the LED on or off depending on the temperature. The tutorial covers the setup and coding for both devices, emphasizing the separation of sending and receiving actions.

What is the purpose of sending random temperature values in the described process?

Explain how the LED is controlled based on the temperature readings.

Describe the role of the 'void loop' in the Arduino code.

What is the significance of using 'Millis' in the Arduino code?

How does the Raspberry Pi read and process the temperature data?

What steps are taken to ensure that the LED is turned on or off based on the temperature?

Discuss the importance of defining a protocol for communication between Arduino and Raspberry Pi.
