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.

Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware ...

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 a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects, you ...

11 Arduino projects that ... Each sensor can be communicated with using I2C from analog pins 4 and 5 on the Arduino Uno. We powered the sensor stick using ... It's for long-distance ...

The Arduino Servo Cat-a-pult looks to automate this rather annoying daily task. A pressure sensor mat — placed in front of your cat’s food dish — activates the device.

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 ...

As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it&#8… ...

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 ...
