The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Circuit Diagram. Here the Nokia 5110 LCD is used to display the Light level and distance.The Nokia 5110 LCD operates at 3.3V so it can’t be connected with Arduino Nano digital pins directly. So add ...

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 ...

Ultrasonic Sensor Arduino Circuit Diagram and Explanation. The circuit diagram for arduino and ultrasonic sensor is shown above to measure the distance. In circuit connections Ultrasonic sensor module ...

This project uses an ultrasonic sensor to measure distances in centimeters and controls a set of LEDs based on those distances. The project is designed for Arduino boards, and you can use it to build ...

Title: Uploading Distance Data from an IR Sharp Sensor to ThingSpeak Using ESP32 and Arduino: A Step-by-Step Guide Introduction: In this step-by-step guide, we will explore how to retrieve distance ...

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.
