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.

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

Besides the Arduino’s serial monitor, we also used our DSO to measure pulse output from the water flow sensor. In that crude experiement, serial monitor displayed a rate of 56 Litre/hour (in lieu of ...

Finger Bend is a unique DIY Arduino powered textile flex sensor, created as part of the Swatch Exchange, enabling you to trigger actions by simply bending ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

Arduino is a do-it-yourselfers dream that allows you to create a true smart home experience tailored to your needs. Check out how to use Arduino to build the smart home you want.

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

In just 100 seconds, learn how Arduino works - from its microcontroller and architecture to how it's programmed and used in real-world projects. A fast, simple intro to one of the most powerful tools ...
