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 ...

🛠️ Components Used 🔹 Arduino Uno – Microcontroller for processing sensor data. 🔹 HC-SR04 Ultrasonic Sensor – Measures distance using sound waves. 🔹 LEDs (5x) – Visual indicators for different ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Smart Blind Stick using Arduino Circuit Diagram. The below circuit diagram shows the complete hardware wiring setup of the Arduino-based Smart Walking Stick for the Blind people, detailing how the ...

In this project, we will build Human Following Robot using Arduino and Ultrasonic Sensor. This robot can track and follow a person autonomously, ... // Function to measure the distance using an ...

Analog ultrasonic sensors require a timer circuit (or a host controller) to carry out the timing necessary to determine distance. However, digital ultrasonic sensors integrate the timing and decoding ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...
