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 sensor forms an image and OpenCV detects the actual touch configuration. It appears you can use the raw data from the Arduino, too, but it might be a little harder. We imagine aluminum foil ...

And the Touch Board from Bare Conductive wants you to combine your DIY spirit with the ability to turn practically any surface into a sensor. At the heart is an Arduino compatible microcontroller ...

Project Overview “In this Instructable we’re going to build a budget spinning LiDAR sensor, powered by Arduino. It cost less than £30 to build ($40) and has a diameter of only 30mm (1.18″).

Electrical projects can seem intimidating, but we found battery operated motion sensor beams that will light up your house. This easy install is the perfect DIY lighting project to get the most ...
