![]() When you have to define properties for multiple Arduino pins, you can do it easier using for loops. note durations: 4 = quarter note, 8 = eighth note, etc.:įor (int thisNote = 0 thisNote < 8 thisNote++) Ĭonst int numTones = sizeof(buttonPins) / sizeof(buttonPins) This example code is in the public domain. You can use the code below to test the circuit and also complete the first project. > Learn more about How Easy Is It To Learn Arduino here.Ĥ) Arduino Program to create a simple Melody using Piezo buzzer The above buzzer can work from 3V to 24 V hence this is a good choice. Quick Tip: Buy the Buzzers, which are compatible with Arduino UNO. Pushbutton x 8 ( for the Arduino mini-piano project).Arduino USB cable (for powering and programming) x 1. ![]()
