Today we present a Bridge between Raspberry Pi and Arduino that leverages the hardware equipment and the computing power of the first with the shields and the applications of the second. The worlds of Raspberry and Arduino increasingly tend to converge to give users a bridge between the enormous potential of the embedded Linux platform…
It is always convenient to dispose of an easily adaptable module that can play musical tracks: it allows to easily implement vocal syntheses to insert within a promobox, or to place items in the shop windows or in well trafficked areas, or close to automatic doors or to turnstiles, or to other…
Here we present a small, low cost single channel receiver, encoding MM53200 and HT-12, with code self-learning function. Decoding is achieved by means of a PIC microcontroller by Microchip, that deals even to the memorization of 5 codes and governs the relay output as well. Features – Number of outputs: 1 – Output:…
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…
Here we are, a great year full of innovations and open source project is passing by and we would like to celebrate with you this magic moment! As usual in this period, it’s time to take stocks of the work done so far, so here are the most visited posts on Open Electronics. Top 5…
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…
Here we present our first tests with the Pixy camera, a device capable of detecting the colour of the objects, and to track their position. Until a short time ago, it was really difficult to develop applications able to take advantage of artificial vision algorithms, and most of all by using systems with limited hardware…
After having seen the features and potentialities of RFTide modules, let’s see how to create a small network that has all the features of an advanced mesh network. To create a network with the RFTide modules, it is necessary to have at your disposal at least a Master unit. For the moment, let’s say that the…
A recent research, from two important universities in Spain and in Germany, states that learning a new language stimulates the same part of the brain as having sex or eating chocolate. Of course we cannot help you with the first two things (for now, at least), but from today on we do help you with…gluttony!…
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….
Here we are, eventually the contest has come to an end and after a short consultation we have chosen the winners! Before announcing them, a few words. First of all, thanks to everyone who submitted his contribution. All the works reviewed are great and must be praised, because they represent without exception a hard work,…
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,…
Open-Electronics.org is the brainchild of a world leader in hobby electronics Futura Group srl. Open-Electronics.org is devoted to support development, hacking and playing with electronics: we share exciting open projects and create amazing products!
Open-Electronics.org is not just a container of ideas: it is also a web site lead by a team of engineers and geeks who will take part in the discussions and give support.
Our mission is to become a reference Open Source hacking site with ideas and feedback aimed to enrich the community.
