The provided Arduino code performs the following actions: Initializes pins and serial communication. Measures the distance using the ultrasonic sensor and calculates the distance in centimeters.

Ultrasonic-Sensor-with-Buzzer In this project I have created a code for an Ultrasonic Sensor in the Arduino IDE. If an object is present within 10cm of the sensor then buzzer will work.

Human Following Robot Using Arduino Code Here is a simple 3 Ultrasonic sensor-based Human following robot using Arduino Uno code that you can use for your project. This code reads the distances from ...

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...

Our schematic consists on 3 elements which are: Photoresistor (LDR), Piezo Buzzer, 1 – 10 kΩ. The LDR can be connected any way you want because doesn’t have polarity. For resistance you can use from 1 ...
