Serial Communication: Arduino Course 4.9

This tutorial covers the basics of serial communication between an Arduino and a computer using a USB cable. It explains how data is transmitted in bits and bytes, introduces key functions in the Arduino Serial library, and demonstrates how to use the Serial Monitor for data visualization and debugging. The tutorial also highlights the importance of understanding baud rates and the role of the USART hardware in serial communication.

How can you visualize the data being sent from the Arduino to the computer?

What role does the serial monitor play in Arduino programming?

What is the difference between 'Serial.print()' and 'Serial.println()'?

Why is it important to avoid using digital pins 0 and 1 for other hardware when using serial communication?
