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.

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.

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 ...

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 ...

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 ...

Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...

Sure, modern paper shredders already have sensors that tell you when the bin is full, but if your machine lacks this feature, you can just build it a custom sensor with an Arduino Uno.

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Literally, ATtiny85 is a scaled-down version of the Atmega microcontroller on Arduino boards with just a few I/Os (five usable pins) that can listen to or talk to most sensors and transducers.
