Just press the “Copy” button on the top right of the code text field for it to automatically highlight the whole code for you. There is a pretty huge amount of code in this Sketch.
Using an Arduino Unoīelow is an illustration of how to connect the buzzer and resistor to an Arduino Uno.īelow is an illustration of how to connect the buzzer and resistor to an Arduino Nano. Another idea is using a potentiometer instead of a resistor to act as a volume controller! For this tutorial we’ll just be using a 1 k ohm resistor.
But you can also lower the resistance to get a little louder sound, and keep the sound quality. You can actually do without the 1 k ohm resistor! If you connect without the resistor, the buzzer will be a lot louder, and the sound quality might degrade. So basically the buzzer, 1 k ohm resistor and Arduino should be connected like this:Īrduino digital pin 3 –> Buzzer –> 1 k ohm resisotor –> Arduino ground(GND) pin. Remember to connect the buzzer the right way, the buzzer has positive and negative pins!
Connect the other side of the 1 k ohm resistor to ground(GND) pin on the Arduino. If you have an Arduino Nano, look the the image in “Using an Arduino Nano”.Ĭonnect the positive side of the b uzzer to digital pin 3, then the negative side to a 1k ohm resistor. If you have an Arduino Uno(which most people have), connect the components with the help of the image below.
