Raspberry Pi and Arduino - Go to The Next Level - Activity 03 - Asynchronous Bidirectional Communication

The video tutorial explains how to set up a serial communication between an Arduino and a Raspberry Pi. It involves initializing a counter on the Arduino, sending its value every 500 milliseconds, and incrementing it. The Raspberry Pi receives and prints the counter. Additionally, every 10 seconds, a command is sent to reset the counter. The tutorial emphasizes non-blocking actions in Python to ensure continuous counter printing and resetting without delays.

What is the primary task of the Arduino in this activity?

• To initialize and send a counter every 500 milliseconds

• To reset the counter every 10 seconds

• To send a special command to the Raspberry Pi

• To receive and print the counter

What additional task must be performed every 10 seconds?

• Initialize a new counter

• Send the counter to the Raspberry Pi

• Print the counter on the Arduino

• Reset the counter by sending a special command

How are the actions of sending and resetting the counter described?

• They are dependent on each other

• They are completely independent

• They occur simultaneously

• They require a delay

Why should time.sleep not be used in the Python implementation?

• It will send the wrong command to the Arduino

• It will reset the counter incorrectly

• It will prevent the counter from being printed for 10 seconds

• It will cause the program to crash

What is the purpose of using a non-blocking action in Python?

• To use time.sleep effectively

• To delay the counter reset

• To ensure the counter is printed continuously

• To block other processes
