The device is based on a GSM/GPRS module with included GPS. Its main function is to detect and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. Its small dimensions are due to the use, for the first time, of a GSM/GPRS module integrating the GPS receiver….
Allows you to create data connections on the GSM network through a standard USB interface. The cellular modems, particularly USB-stick ones, are now at very affordable prices, however they’re limited: they are explicitly designed for Internet connections, so you cannot use it as a normal modem and so implement, for example, a point to point…
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…
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…
We are not the first to make an Motor Shield for Arduino. But could be that we are the first that make a Motor Shield with a minimum of flexibility. We are studing a WiFi robot with camera controlled by Arduino. The robot will be controlled by browser. But we find a problem with an…
PC configuration software for all remote controls described in the last four issues. This application is used to set all parameters via PC, instead of using the boring and expensive SMS configuration system. Download “Configuratore TDG v.2.3.0.0” (Source code VB .NET 2010) In the articles devoted to the remote GSM modules, we have repeatedly mentioned…
Now we can start describing our first application, that is, the GSM gate controller: in this modality, our system controls the relay it is equipped with whenever it receives a call from a telephone number belonging to a list of numbers previously acquired through a special procedure, which can be performed via SMS using a…
Allows to remotely manage the heating or cooling of any room. It can also notify, via SMS or phone call, when the sensed temperature falls out the set limit value or the alarm input is active. In Summer As well as in Winter, it may be a good idea to install at home as well…
The entire remote control is handled by a PIC that controls the GSM/GPRS module’s activity and gives commands to the two relays. Having said that, let’s take a better look at the electric scheme: power is supplied by continuous voltage, not always stabilized (applied to PWR + and -) at a value between 5 and…
