The Complete Beginners Guide to Arduino - 2021 - Making Sound with a Piezo

This video tutorial covers the use of Arduino tone commands to create sounds with piezo sounders. It explains the setup of a simple circuit and demonstrates how to use the tone command to produce different frequencies and durations. The tutorial also explores creating alarm sounds using loops and frequency changes, and generating random sounds with the random command and analog read. Key concepts include the difference between piezo sounders and buzzers, the importance of delays in sound generation, and the use of random seed for true randomness.
