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 usual RFID key, because the system can …

 
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 shield: the Ethernet or WIFI Shield, which provides the connection to LAN, …

 
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 on Ethernet TCP / IP, and so …

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 existing shield: the pin SPI to …

New GSM/GPRS library
 
This is a very low cost and simple Arduino GSM and GPRS shield. We use the module SIMCom SIM900. It’s the cheaper module now avalaible in the market. The module is not simple to mount by an hobbyst, so we use the Breakboard TDGGSM_900 that we presented in this post.
You can buy the GSM module premounted from our cart.
To …

Shield to control 6 relay, 6 digital input and 6 analog input with Arduino Duemilanove, Arduino UNO or Seeeduino. The digital inputs and relay outputs are equipped with an LED that indicates the status. The lines of I/O are connected to the Arduino through corresponding pin-strip pitch 2.54 mm. It gets its power directly from the Arduino module, which provides …
