[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.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller ... Here is ...

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 ...

YouTuber DuctTape Mechanic has published a new tutorial on how you can create your very own Arduino ... proximity or touch of an object. In this case, the sensor detects the impact of the speed ...

Why not create your very own high-speed camera trigger using an Arduino, piezoelectric sensor (as a sound sensor), a DSLR camera, and an external flash. Watch the video after the break to see it ...

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 ...

Likely applications are button designs and proximity sensing. The kit’s board also includes ... The devices and the kit use the EZ-Click software tool to configure capacitive sensing features. Also ...
