Arduino for Beginners - 2022 Complete Course - Change Serial Baud Rate for Faster Communication

The video tutorial explains the concept of baud rate in serial communication, emphasizing the need for matching baud rates on both sides of the communication channel. It discusses the trade-off between speed and accuracy, highlighting that higher baud rates can lead to errors. The tutorial suggests using a baud rate of 115,200 for optimal performance, balancing speed and error minimization. It also demonstrates how to set and test this baud rate in an Arduino setup, ensuring efficient data transfer.

What is the significance of having the same baud rate on both sides of a communication?

How does increasing the baud rate affect data transmission?

What are the potential risks of setting a baud rate too high?

What is the recommended baud rate for optimal performance without errors?

Explain the process of changing the baud rate in an Arduino program.
