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.

An passive buzzer; Arduino board; Breadboard; Jumper wires; 100ohm resistor; The tone of the passive buzzer can be controlled by adjusting the frequency applied to it. With Arduino, you can produce a ...

The Amplifier IC is used to amplify the Output from Dog Barking Sound Module. The Alarm circuit consists of an Arduino Nano, PIR Motion sensor, LM386 Amplifier IC, Speaker, NPN Transistor, and a ...

If you’re bit-less, they’re also now selling an Arduino-centric starter kit with the Arduino module and 8 others (a battery, a few switches, a servo, and a control dial) for $89.

Connect pins 7 and Gnd of Arduino to pins 1 and 3 of KY-008 module, respectively. Run the first sketch (onoff.ino) to turn the laser on and off every second. Next, connect pin A0 (ADC channel 0) of ...

The VersaTap passive tap module provides a low-cost, high-performance asynchronous communication data monitoring and logging solution in a convenient, lightweight package. The device’s unique ...

This paper mainly completes the hardware platform and software design of the wireless car control system. Hardware platform design using modular design ideas, at the same time, using ARDUINO UNO R3 ...

The Arduino Mega can control both active and passive buzzers through its digital output pins, enabling audible alerts and sound generation for interactive projects and notifications. - Projectslear ...
