In this post we present a robotic lawn mower, powered with solar energy and able to operate just with the clean energy…
Since long past times, when Gugliemo Marconi has amazed the entire World broadcasting his radio signals from the Elettra ship, a subject held dear by electronic engineers has been radio transmission. After these years, the scenario has changed a lot, firstly with the appering of digital technologies (DAB, for instance) and, up to day,…
Today we introduce a I/O expansion shield for Raspberry Pi which allows you to extend the number of digital inputs and outputs available for our applications. [See also our previous I/O expander for Arduino] After having published the LCD display and GSM expansion shield we add to the collection a new shield, based on the…
I am not an enthusiast of Raspberry Pi, for a bunch of reasons: indeed I believe that we can find on the actual market so many boards that would make a Raspberry Pi blush in a confrontation uniquely based upon hardware features. The enabling element of the Raspberry is its cost: it has probably the…
Today we’ll expand Arduino’s digital resources thanks to an I2C bus equipped shield and we’ll allow the management of the board via a bluetooth connection RN-42 through an Android systems. All Arduino boards feature a number of digital I/Os. For the simplest projects, such resources are usually more than sufficient, but in those where they…
Trying to figure out what kind of cool stuff you can create with a 3D printer it’s not always easy if you just look to a magazine talking about it or hosting an advertising page: to fully understand what a 3D printer can do for you, you need to start printing. No coincidence that those…
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…
[youtube id=”Ofufxmm6wd4″ width=”620″ height=”360″] Let’s create a plotter to decorate Christmas Tree balls with writing and drawings. 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,…
Today we present an expansion shield for Raspberry Pi to control the very effective GSM/GPRS SIM900 and SIM908 (with GPS) modules: in this way it is possible to extend the functionality of Raspberry Pi for mobile applications (eg: remote control) and, by employing the SIM908 module, even the GPS functionality. Even if we will describe…
