This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

But do you know how this type of sound sensor works? What is it used for? and how to interface a sound sensor with an Arduino? If you have these queries and are looking for answers, then don't worry, ...

It’s an electronic device commonly used to produce and signaling a procces that is happening through a sound, beep or etc. The Piezo buzzer produces sound through electricity. Some uses of Piezo ...

At first, the state of the PIR sensor is set to LOW. it means that no motion is detected. When a motion will be detected by the PIR sensor, it will send a signal to the microcontroller. The ...

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 ...

As well, one red-colored LED (shines like a beacon) provides the visual alert. After construction and testing, you can re-build the whole circuit in a small veroboard, with the help of one ...

Power up the sensor through Arduino and connect the A0 pin of the sensor to A5 of Arduino. Connect a buzzer and an LED in a parallel configuration. Connect their one end to the ground of Arduino and ...
