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

Easily connect Arduino boards at a great distance over RS485 with Visuino.

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...

The unit developed here makes your appliances like TV, amplifier, CD and DVD players control with voice commands using Alexa and Arduino.

Make simple math with arduino UNO

An Arduino based word clock that tells the day of the week, the month, day and year and the time to the minute in words.

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

One code goes in, another comes out... A different way of having a single remote without needing a universal one.

A simple yet functional button based MIDI piano.

The correct way to make traffic lights for a 4-way intersection.

Designed for crew rowing, this speedcoach is designed to track split times and total meters traveled.

Arduino Nano based relay power switch for Raspberry Pi 3 (Kodi) operated by common TV remote controller.

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

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

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

Cheapest and easiest Nixie clock in the world, the ONE TUBE™. Open source is the way. ( or use, UNO-Pro Mini/Micro-ESP )

A simple to build clock with many features.

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

I sleep a lot. For this, I wanted to make a timer. I want to sleep just four hours. Life is very short!

Make a Linux distribution that is focused on the development of Arduino and IoT. It's a Distro for Arduino.

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

Build your own word clock with an animated display. Includes a stylish 3D-printed case and five animation patterns.

In this project, you can measure typically up to 48V. It is recommended to use Arduino digital voltmeter as “0-48V DVM”.

In this project some brilliant ideas found in the Internet are combined together.
