This library is designed for piezo buzzer to beep or play memody without using delay() function. Every wave has an associated property called frequency which measures how many cycles happen every second. When voltage is applied to a piezoelectric ceramic material it causes it to vibrate rapidly, resulting in the generation of sound waves. Hi i was a question about why piezo buzzers make weird sounds when used without a resistor. How does it work? It's simple, tone(buzzer, 1000) sends a 1KHz sound signal to pin 9, delay(1000) pause the program for one second and noTone(buzzer) stops the signal sound. Basics Most times a piezo buzzer is used to produce sounds with an Arduino. CDs store 16-bit audio, which means there are 65536 possible values. This is enough to allow us to play two square waves simultaneously: High-quality audio requires many more values than this. For more interesting projects connect with me on: Youtube. So we now have three possible output values: on, off, and halfway.
