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

The video tutorial introduces a new activity where data is sent from an Arduino to a Raspberry Pi, processed, and a response is sent back. The challenge involves sending fake temperature data and controlling an LED based on a threshold. The tutorial explains multitasking without delay, using random numbers for temperature, and processing data on the Raspberry Pi. It concludes with code reuse from previous activities.

What is the main challenge introduced in the new activity involving Arduino and Raspberry Pi?

• Sending light intensity data from Raspberry Pi to Arduino

• Sending audio data from Arduino to Raspberry Pi

• Sending video data from Raspberry Pi to Arduino

• Sending temperature data from Arduino to Raspberry Pi

What happens if the temperature sent from Arduino is below the threshold?

• The LED is powered on

• The LED changes color

• The LED blinks rapidly

• The LED is powered off

Why is it important to avoid using delay in the Arduino loop?

• It causes the LED to blink

• It stops the Raspberry Pi from processing data

• It blocks the program and delays data reception

• It increases the temperature

What technique is suggested to handle multiple tasks in Arduino without delay?

• Using multiple loops

• Using delay function

• Using a single thread

• Using multitasking structure

How is a random temperature value generated in Arduino?

• Using a fixed value

• Using the random function

• Using a temperature API

• Using a temperature sensor

What is the first step in processing data on the Raspberry Pi?

• Calculating the average temperature

• Turning on the LED

• Reading data from serial

• Sending data to Arduino

Why is it beneficial to reuse code from previous activities?

• It requires more resources

• It increases the complexity

• It saves time and effort

• It is mandatory for all projects
