[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.

After some searching, I ended up using a microcontroller and a piece of code ... Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Trump overpowers Musk's ...

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 ...

Instead of measuring light, we measure the ambient voltage field on pin A5 and use ... Arduino. A5 is used as a “floating input”, but unfortunately it is very noisy. The usual solution is to use some ...

We’re used to Hall effect devices as proximity sensors in mechanical ... The circuit is extremely simple, comprising the sensor, an Arduino Nano, and an OLED display. This device is handy ...

The CY3280-MBR3 CapSense MBR3 kit can be used to evaluate the third generation of Cypress Semiconductor’s capacitive-sensing technology. Likely applications are button designs and proximity sensing ..
