Today we’ll explain how to exploit the potential of Arduino as a programmable logic controller, connecting it to appropriate interfaces for I/O. The PLC (Programmable Logic Controller) has been and still is the basic component of the...

This robot will mow the grass of your garden, staying within a defined area, avoiding all obstacles and working in complete autonomy, automatically charging itself with a solar panel. In this post we present a robotic lawn...

Use Arduino as a Xively HTTP client and interact with the new shield for power management. We already talked about WiFi connectivity for Arduino in other posts, presenting the design of a high performance WiFi shield and...

The series of posts devoted to the OpenWheels platform continues with the description of the processes related to the verification and management of the data collected from the sensors through a dedicated telemetry software .   At...

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...

In order to “visually” highlight the behavior of Arduino programs you must connect a device to the I/O pins, which gives you tangible signals. Normally, if you want to check if a program changes a level of...

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...

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,...

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...

  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...

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...

  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...

  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...

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...

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...

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...

  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...

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...
