Simple, easy to build 2 x 14 bars stereo VU meter for representing audio level.

2 x 16-band audio spectrum analyzer with Arduino Nano and 2 x 16 chars LCD display. This project is based on Shajeeb's project.

A stereo VU meter built with an Arduino Nano and two NeoPixel LED rings.

An interactive robot that anyone can make! Otto is very easy to 3D print and assemble, walks, dances, makes sounds and avoids obstacles.

Improved version of the soldering iron controller for Hakko 907 iron. To simplify building the controller, LCD screen is implemented.

Arduino Nano 32x8 LED matrix displaying date, time, temperature and humidity with a motion sensor.

UltrasonicEyes is a fun and quirky project you can place somewhere and watch as it looks at things moving around in front of it. Freaky!

Yet another useless Arduino clock, but i love it.

Someone has been eating my cookies! Thankfully Arduino is here to help find out who it is.

In this project, I will make an indoor gardening system to take care of my sweet plant and its beautiful flowers.

A digital clock using minimum components.

A very useful project, made to monitor system resources without opening Task Manager.

This is an easy to build pet feeder with two timers and accurate portions delivered each time.

Complete Digital Clock including many features: Alarm, Temperature, Humidy, Dew Point, RTC and PIR (Presence Infrared Sensor).

I built a simple wood LED clock, using modern electronics and traditional wood and metal working techniques.

Another clock project with 1, 2" matrix display.

Here is a step by step guide to making a "crawler robot."

Christmas is near!

Arduino stopwatch and lap timer with excelent accuracy and responsiveness!

Just connect your Arduino smart home and control the heater, airing, and lights via Bluetooth!

Lock and unlocks your door from a desk using a remote.

Hugo just turned one, and to celebrate we bought him a Duktig kitchen from IKEA. I added a working microwave.

This wirelessly controlled robot car uses gesture: tilt/orientation of hand to drive forward, backward, left or right.

One year ago I built a simple Arduino dice with my son. We have learned a lot in the meantime and it's time for an update...
