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 ...

This project is as straightforward as it gets, describing all the steps in great detail, ... The treat in question is detected by an SR-04 ultrasonic distance sensor connected to an Arduino Nano.

It features over 5,400 projects, ranging from simple tutorials — like using a soil moisture sensor with Arduino — to more complete guides like building a Bluetooth-controlled car.

The magic lies in Arduino's Modulino nodes, which consist of various sensors and actuators that connect to the UNO R4 WiFi board. The Plug and Make Kit is a complete package to get started. Inside ...

Arduino is able to interpret signals from a variety of sensors. By placing a unit equipped with an ADXL345, an accelerometer for detecting motion, or a Piezo sensor on a door, it can notify you ...

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 ...
