This project demonstrates how to use a buzzer module with an Arduino Nano to produce sound or generate alerts. Buzzer modules can be either active or passive, each requiring different driving methods.

How to use a Passive buzzer with Arduino? The Passive Buzzer connection to the Arduino is exactly the same as what we’ve done with the Active Buzzer. We can use a PWM output pin to control the passive ...

The point was to learn how to take the most basic circuit connected to an active or passive buzzer and generate musical notes by toggling the circuit HIGH/LOW, and then see how effectively chords ...

In this project, the ultrasonic sensor module type KY-050 is used together with an Arduino and a type KY-012 active buzzer to help while reverse parking our vehicle. As the distance to the objects ...

In this project 0.91” inch I2C Serial 4-pin OLED display module is interfaced with Arduino, It displays number of detected whistles and time duration. The resolution of the display is 128 X 32 and its ...

Circuit diagram for interfacing of KY-008 laser LED module with Arduino is shown in Fig. 2. Fig. 2: Circuit diagram for interfacing laser LED module with Arduino. Connect pins 7 and Gnd of Arduino to ...
