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

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 ...

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 ...

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

[Mike] lives in a temperate rainforest in Alaska (we figured from his website’s name) and uses a 570 gallon oil tank to supply his furnace. Until now, he had no way of knowing how much oil wa… ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

The sensor package comprises an ultrasonic distance sensor, a microcontroller running Arduino firmware, a micro-SD card for datalogging, a real-time clock for timekeeping and sleep functions, and an ...

The design was prototyped using an Arduino, which controlled an LED through feedback from an ultrasonic proximity sensor. The LED would flash into the user’s peripheral vision, glowing when the sensor ...
