Overview / Usage

Making sound on the arduino is an interesting project, this con be accomplish using different modules and devices depending on your project and choices. In this project, we'll be looking at the way you can make sound with a buzzer. Buzzer used by hobbyist come in two types: The active buzzer and the passive buzzer. For this project, we are going to be using an active buzzer. Check out my tutorial on using a passive buzzer.

An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage. To generate tone with an active buzzer, all you need is a DC voltage. Most active buzzer can be powered with 3-5V.

An active buzzer can be controlled from an Arduino pin, very similar to the way you turn on and off an LED using digitalWrite.

Methodology / Approach

MATERIALS

Active Buzzer

Arduino Board (Uno in this case)

Jumper wires

You can use any digital pin of the arduino for the positive pin and connect the negative pin to ground. There is need to use a resistor since the buzzer operates on 5V. You can recognize the positive pin by looking at the top side of the buzzer, you will a point marked "+", the pin on this side is the positive pin.

NOTE: Its not advisable to control the buzzer using analogWrite i.e. PWM.
