Teach kids how colors are made with the color machine

Wednesday, April 9th, 2014

color machine

The Color Machine (La macchina dei colori, in Italian language) is a tool to teach children about the use and the operation of RGB color coding, which is used in all digital devices (TVs, smartphones, computers, etc.). It was created with Arduino Mega by an italian duo composed by Fabio Ghidini and Stefano Guerrini:

Using 3 knobs you can increase the percentages of red, green and blue separately, and the LED strip at the top of the machine lights up consistently with the color mix choosen. (more…)

How to monitor a domestic photovoltaic plant with Arduino

Tuesday, April 8th, 2014



ArdaSol is the name of a project for a solar energy monitoring system based on Arduino Mega and UNO, made by Heinz Pieren. It’s a system built to monitor energy production and consumption of a domestic photovoltaic plant:

The ArdaSol Energy Monitoring System has 3 devices:

- ArdaSol Display based on a Arduino Mega Board
The master of the system, it collects the data from the two other ArdaSol devices, shows the data on the display, stores it on a SD card and sends it to a server in the internet.

- ArdaSol Energy Monitor based on a Arduino Uno
Measures the consumption of the energy, shows energy values on local display and delivers it on request to the ArdaSol Display.

- ArdaSol Remote PVI Interface based on a Arduino Uno
The photovoltaic inverter (PVI) has a RS485 interface, this is connected to ArdaSol Remote, which interacts as a gateway to ArdaSol Display. It converts the requests, coming with a radio signal to the PVI and vice versa.


Growing your veggies with a smart greenhouse called MEG

Tuesday, April 1st, 2014

MEG presented at PopupMakers

MEG is the world’s first social and automated greenhouse, part machine and part community, now on Kickstarter. Carlo D’Alesio and Piero Santoro, the designer duo based in Milan presented the prototype  at Maker Faire Rome and also at a PopupMakers event last year.

MEG means Micro Experimental Growing system, runs on an Arduino MEGA 2560 which controls an automated “light engine,” water and nutrient tank, fans and sensors monitoring humidity, temperature, and pH. It’s smart because if you are not really good with growing plants, you can crowdsource parameters from other gardeners: your neighbour’s tomatoes won’t be more red than yours!



An electronic diesel engine controlled with Arduino Mega

Tuesday, February 25th, 2014

A few years ago Sven and Juho started working on the same type of project without knowing about each other and only by a coincidence their paths crossed. They wrote me about their cool story and the successful experiment of upgrading a diesel engine using Arduino Mega: (more…)

TouchSynth – A high school senior project

Thursday, December 19th, 2013


Steve Mostovoy and his partner Tim Boy Jr, worked for over 9 months to  create a TouchSynth and share all the documentation about it.



It was hard but they learnt  a lot about how not to organize code, how to think in terms of data, and how many amazing things you can do on a 16MHz processor:

This project uses an Arduino Mega, a resistive touchpad, and an 8×8 LED matrix to create a simple digital audio workstation and synthesizer. You can compose and play songs in real time and use different types of sounds. It was a nine month process between me and my partner during our senior year of high school to create this. The result is a really nifty Arduino project that showcases the flexibility of Arduino devices, and it sounds good as well!

Take a look at the video to see how it works:

A diy solar-thermal-powered car in sunny La Paz

Wednesday, November 27th, 2013


Alexander Carl is a Canadian engineer designing and building one of the world’s first diy solar thermal powered car in sunny La Paz in Mexico. He contacted us through Arduino Facebook page to show us his project developed  using  Arduino Mega to sun track the 24 x 6 foot curved mirror, to sense the temperature and pump hot oil and many other things. You can find a lot of pictures on the project page on Facebook. (more…)

Using Arduino in a semi-automatic production line for casting polyurethane foam

Tuesday, November 19th, 2013


Alexander Kozusyev wrote us from Kiev to share how he introduced Arduino in his semi-auto production line creating decor by casting polyurethane foam.

Production line has two independent CNC 3-axis manipulator. The first spraying of release agent. Second automatic pouring polyurethane into the mold. Before spraying or pouring read RFID unique code for the mold, and then loads the G-CODE from the database server based MySQL. After pouring, the mould is moved to the waiting area.

He used Arduino Mega to read RFID codes and to  control some components, an Arduino Uno with firmware GRBL version 0.9 to control the CNC. Take a look at the video:

An open source robotic lawn mower

Monday, November 18th, 2013



Ardumower is a project with a basic aim: making a new ‘brain’ freely available for every robot mower in the universe! They  use Arduino Mega and a selection of electronic components including motor driver and sensors.

Why did we create this project?

We did create this project because we think robotics should be open and this includes robotic mowers as well.

Objectives of the project:

- Low-cost, ready-made components, replaceable (à la RC model: stick together receiver, controller, motor, servo !)
- Little soldering – easy programming only the minimum of components (keep it simple!)
detailed instructions for building
- Offering a construction kit (ready ‘Ardumower-kits’) with all modules, components etc. for purchasing
- Free, open-source Arduino-Code for download
- Finding a producer for a robot chassis (‘Ardumower’ chassis)


Find documentation, code and  list of components on Ardumower website,  in english and german!

Carpentry, circuit design and coding for an interactive instrument

Tuesday, October 22nd, 2013

field lines

Field Lines is an interactive instrument designed by composer Charles Peck as part of his Threshold of Beauty project. On his website, Charles says that the installation is his largest piece to date:

Constructing this substantial piece of equipment drew on a number of disciplines including physical design, carpentry (an occasional hobby of mine), circuit design, and coding. As alluded in the title, this piece focuses on the magnetic field. There are three sections of magnetic material, including magnetic sand, a compass array, and zinc-plated iron. Audiences are able to manipulate these materials with a magnet in the space below each case while infrared sensors pick up their movement. The sensors send that information to an Arduino board, which then creates unique music for each section.


A cake maker with a passion for engineering and Daft Punk

Thursday, July 25th, 2013


Shantal Der Boghosian is the owner and cake decorator of Shakar Bakery, but also an engineer and a chemist based in Los Angeles California. She recently wrote us to share her 5ft (152cm) tall tribute cake for Daft Punk, the French electronic music duo, and created together with her sister and Garen (coder).

DaftPunk1 DaftPunk2 DaftPunk3

The cool thing about this project is that the bodies of the band are made of cake and the heads move at the rhythm of the track “Get Lucky”, controlled by Arduino Mega.

This project took 2 months to design, over 100 hours to build the structure and another 100 hours spent on the electronics, programming, and mechanics . We had a lot of bumps in the road and we worked through every single one. This was the first time I ever built a cake structure, the first time I sculpted with rice krispies, and the first time I built a cake on such a massive scale! This was Garen’s first time coding an Arduino servo, and creating head motions that defied weight restraints! I have to admit that we did a last minute surgery to the silver helmet to make the “no” motion more fluid.

Enjoy the video below and take a look at her detailed blogpost with all the phases of the complex yummy construction!
