[youtube id=”tCZE3e39XkM” width=”620″ height=”360″] Just a few weeks ago, we presented in this blog the maker version of a motorized snowplow, similar to those available in many bricolage shopping malls. In fact our robot is a particular caterpillar track, a miniature version of the traditional snowplow but that can be radio controlled easyly with…
We will equip Arduino with wireless connectivity basing on MRF24J4 module by Microchip. As a sample application, we will remotely control a relay, operated by a floating input, and we will virtualize the Arduino USB serial port. The MRF24J40MA radio module is manufactured by Microchip, that also provides useful and complete software libraries…
We present a caterpillar robot based on Arduino Uno, remotely controlled through a Play Station 2 wireless controllers. Since we are not insensitive to solutions making life easier, we have considered the idea of creating and proposing something that could help us avoiding the cold and fatigue of using the usual manual shovel and…
Putting in contact the wireless world of the mesh networks with the world of Arduino allows the developers to create new and interesting applications, particularly in the field of domotics. To reach the objective, we created a dedicated shield (called RFTide shield), purposely made to manage the basic RFTide modules with Arduino in an easy…
We’ll show you today how to use the WiFi shield and its libraries to turn Arduino into a Web Server; in addition, we are going to use the I/O Expander shield to provide more input and outputs to the platform. We will describe how to handle the specific library to use the WiFi shield as a WEB client for a public website that will collect data coming…
Today we’ll show you how to feed a whole Arduino system from a battery, optimizing energy consumption to ensure that the batteries would provide power to the complete system for few years. Perhaps, the only shortcoming of Arduino is that there aren’t any sophisticated tools in case you want to use a battery power supply….
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 industrial automation world. The Industrial application made the PLC systems being very expensive, both to buy and repair,…
[youtube id=”eINAuYg-ftM” width=”620″ height=”360″] 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 mower, powered with solar energy and able to operate just with the clean energy…
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 explaining how to use it both as a web server, or a web client. The two modes of…
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 this point in the project, OpenWheels board is widely tested and ready to work with its firmware. It…
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 digital I/Os. For the simplest projects, such resources are usually more than sufficient, but in those where they…
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 an output pin, answering a command or executing a check routine, or event, you must check it by…
