This short report is aimed to the most “advanced” users of Arduino boards, especially to the users of the “Mega” flavors of the family, but also users of standard versions of the board, like Arduino UNO and Arduino Duemilanove, can take advantage of the following notes. The story starts with the TiDiGino, one of the…
We use an Arduino to program other ATmega without bootloader . This technique allows you to use all flash memory for code and make boards using new ATmega, cheaper than those with bootloader. The qualities that have made the success of Arduino are undoubtedly the open-source software, many libraries, a good hardware and a virtually infinite…
A Thanks to Chris Anderson, Massimo Banzi, Dale Dougherty and the MAKERS of the new Industrial Revolution. On March 9 in the Acquario Romano we heard testimonies of people, reality and Italian companies that have never stopped believing in innovation. We like the stories of those who invest in their future without fear and looking to new technologies. Just as we love the old craftsmen who know how to reinvent traditions. We know that it takes courage to get involved. World Wide Rome has shown us that there are opportunities to do…
This shield could be used as a stand-alone transponder key, or with Google’s servers to create a cloud-computing application. It’s time to present you an application with RFID. We want to show you how to use the popular Arduino to produce a device capable of recognizing passive transponder (TAG). But this is not the…
![ARDUINO WIFI RGB LAMP [IKEA DUDERÖ MODDING]](https://oe2.open-electronics.org/wp-content/uploads/2012/02/Draft-768x332.webp)
[iframe_loader src=”http://www.youtube.com/embed/_TeYH0ZqGm0?hl=it&fs=1″ height=”349″ width=”425″ ] We create an application based on Arduino, that allows you to control brightness and color of a RGB strip LED via local network or Internet through a WiFi or Ethernet shield How it works The system that we propose is based on the Arduino UNO, on which are mounted two…
A lot of people who bought the TiDiGino ask me how to test it. The Gsm Remote Control is provided with bootloader, so you have to insert the prefered sketch that you can find in code.google. Daniele Denaro wrote a good sketch for TiDiGino, and I’m reporting his tutorial. Ask me (and him) all do…
[iframe_loader src=”http://www.youtube.com/embed/beqdlg89I5o?hl=it&fs=1″ height=”349″ width=”425″ ] This module integrates the sensor MMA7455L (produced by Freescale), able to detect the movement on three axes, and then in every direction. The chip offers the possibility to select three different sensitivity (± 2g, ± 4g, ± 8g) and makes available, on an SPI bus and the I ²…
The shield most used in practice are those that expand the communication of the Arduino board and in particular those that allow to add a network connection to a TCP / IP. The first shield of this kind were those based on Ethernet technology, which helps the Arduino to connect to a LAN based…
Using an ATmega 2560 and therefore the heart of Arduino, we have developed a universal remote control with GSM. This allows to control 2IN/2OUT, DTMF key, gate control and GSM thermostat activated remotely. We have already presented several remote control with different functions. But now we want to present the best remote control ever…
[iframe_loader src=”http://www.youtube.com/embed/-UILW2sY4IY?hl=it&fs=1″ height=”349″ width=”425″ ] In the previous post we showed you how to make small Christmas shapes using an RGB LED and a small circuit based on PIC. The designs were obtained working with the CNC some acrylic sheets. But our CNC can do much more … Therefore we decided to make the greatest…
There are several softwares that enable the publication of the weather data of a professional weather station, but they all work on PC, so we should connect the weather station to a computer and leave it on, the idea is not good because the computer takes up space and consumes a lot. At a…
I love IKEA and her low cost products. Last week I found this STRÅLA lamp. The cost is $4.99, so I bought it. Lighting the lamp I saw that it ‘s very pretty but also … too soft… So I thought to modify the LED and add a RGB led. With simple modify you can obtain a dinamic…
