[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 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.

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.

Finally, your Arduino toolkit will be incomplete if you don't purchase some sensor and circuit modules. After all, you can’t build a precise weather station without a BME280, DHT22, DS18B20, or ...

These projects will sharpen your hardware and software skills, including arduino programming, sensor, signal processing, smartphone software programming. Project outcome The specific outcomes of this ...

The MyoWare muscle sensor project is currently over on the Kickstarter crowd funding website looking to raise $10,000 in pledges to make the jump from concept to production.

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 ...
