Arduino (any compatible board), HC-SR04 Ultrasonic Sensor, Jumper Wires, Breadboard (optional), #Circuit Diagram: Trig Pin of HC-SR04 → Arduino Pin 9, Echo Pin of HC-SR04 → Arduino Pin 10, VCC of ...

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 ...

Now, the venerable ultrasonic sensor joins the gallery of classics given a size change treatment, like the 555 timer we’ve seen two different takes on, or perhaps that one Arduino Uno.

This project utilizes an Arduino microcontroller along with an ultrasonic distance sensor to measure distances and provide warnings when objects are detected within certain ranges. The distance ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

In this mode, you place the Ultrasonic Experiment set facing an object up to 200cm away, and press the “SEL” button to take a sample of the distance. Once the sample has been acquired, the LCD ...

This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display information ...

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 ...
