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…
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…
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…
Here’s an application to control the brightness of an RGB LED strip wirelessly (via Bluetooth) using a smartphone. The whole project is presented in a dedicated Bluetooth shield for Arduino and a RGB shield. The Bluetooth Module You’ll know already that the market is full of different Bluetooth modules: these modules are all based on…
In this post we will deal with an interesting solution to overlat text on a video signal. This solution, which uses the LM1881 integrated, has a lot of use cases accompanied by variable software challenges. For this reason this post is a kind of tutorial, presenting no vertical solution, but instead providing an overview…
Electricity costs are rising, and just in case this is not enough, if you exaggerate with consumption your house circuit often stops working in the very moment of your greatest need. This project allows you to keep an eye on your electricity instant consumption even remotely. [iframe_loader src=”http://emoncms.org/boris&id=2505 ” ] The acquisition of current consumption…
Once again we have prepared some examples related to the GSM/GPRS & GPS shield. In previous posts we have seen how to handle SMS, make calls and use the GPRS connection to send email or download data from Internet pages. The shield has been developed to accommodate both forms of SIMComs: SIM900 and SIM908: the…
Let’s expand RaspberryPi functionalities with a shield that is compatible with the Arduino pinout and with an onboard analog to digital converter with 16-bit resolution. Further expansions that we will present in the future will allow you to add a DAC, a number of additional digital I/Os and the ability to connect also with non…
After having shown several examples regarding the use the GSM/GPRS & GPS shield with calls and text messages we are now going to present some applications that involve GPRS data. Thanks to the inet.h class the shield can indeed connect to the internet and its various applications. We ‘ll see how to use the Arduino as…
This post is one in a series showing you the main features of the GSM /GPRS/GPS shield and of its related library. The examples are great to have inspiration and reuse the material to create your own solutions. We already talked about how to use the shield to make calls, send DTMF tones and…
A few months ago, we presented a powerful shield that can enable devices from the Arduino family (Uno and Mega) to interface with the SIMCOM modules SIM900 and SIM908. Such modules provide integration with the world of GSM, GPRS and GPS and all is achieved through very simple Arduino commands thanks to the open-source dedicated…
