[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. The ...

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 and a piece ...

Today, we’re going to explore the uses of addressable LEDs. Addressable LED is an easy way to add complex lighting effects to any project. Each addressable LED has an integrated driver that allows you ...

So you finally decided to hop on the Arduino bandwagon and start making electronic projects as a fun hobby. As a beginner getting started with Arduino, your first instinct is typically to buy a ...

We’d seen it done with buttons, switches, gestures, capacitive touch, and IR remote, but never like this. [electron_plumber] made an LED that can be blown out like a candle, and amazingly it requires ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...
