In order to “visually” highlight the behavior of Arduino programs you must connect a device to the I/O pins, which gives you tangible signals. Normally, if you want to check if a program changes a level of an output pin, answering a command or executing a check routine, or event, you must check it by…

We know that, as it’s Valentine’s Day, looking at the device described in this post you’ll be inclined to think that this is the usual…
Since now on, it will be easy to provide your Arduino with Internet connectivity by using this shield. The shield sports a TCP/IP stack manager, in order to free up the Arduino from some basic tasks. It’s also essential to equip the board with a library, that communicates with the TCP/IP manager and makes it…
The Lewe project aims to collect and use available technologies to make a low cost idea that is applicable to all sectors using sensors for data collection. This project goal is the development of a communication protocol, named Jack, able to transport data reliably making communication between multiple devices easier and real-time. All this could…
To create a PCB with 3Drag , by milling , it is necessary to have the G-Code files for the tracks patterning and for the holes relating to the printed circuit board itself. In this section we describe how to obtain these G-Code files using a specific plugin for the popular PCB design software ”…
How to create the G-code files from any gerber file (using PCBMill software) necessary to create a PCB with 3Drag, by milling. To create a PCB with 3Drag, by milling, you need the G-Code files for the tracks patterning and for the holes pertaining to the printed circuit board itself. In this section we describe…
[youtube id=”euv3kv9kpEg” width=”620″ height=”360″] After a fair amount of work we can finally presents you a tutorial on how to modify our 3Drag printer or K8200 printer to transform it in a perfect CNC milling machine, to be used for the production of PCBs, by incision. In addition, we also show you the procedures to…
Let’s capitalize on the Yun Arduino new features to create an electronic “guard dog”, which allows you to watch your stuff, a hidden corner of the backyard or our car silently laying in the garden. Here we wanted to face a small project, but one you would not be able to do with old Arduino…
By coupling a standard NMEA GPS receiver and an Arduino board we created a super simple and effective Arduino GPS logger. This device allows you to trace the route taken by a person or vehicle (or any other moving object) by simply doing a periodic caching of location points coming from the GPS unit. As…

Christmas is coming you dusted off your xmas tree and decorated it: everybody try to make it different, buying new decorations and balls of different colors. Well, if you are looking for something original, think of making your…
This post is about a light animation game that can light up your Christmas. There’s Bluetooth, Android and audio files: a perfect festive mashup. A spectrum analyzer will help us color the winter festivities. Every year at Christmas we always want to try something new for lighting up our decorations: everyone wants to impression…
With the new RN-42 Bluetooth module we created a Bluetooth remote control board and transform it into an Android Based system: a board that manages input/output and it’s equipped with four outputs relays and four optically isolated inputs, that can be controlled via Bluetooth. At the software layer, the unit sports three operation modes: manual,…
