Arduino Project: Generating Sound with a Passive Buzzer
In this Arduino project, we will be using a passive buzzer to generate sound. Similar to the active buzzer example, you will need to connect the buzzer to the Arduino. The buzzer has a positive “+” pole, which can be connected using a red wire (a good habit to follow). Connect the negative “-” wire to the GND on the Arduino and the “+” wire to a digital output pin. In this case, we will be using pin #8....
