[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…
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…
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…
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…
The Christmas eve is approaching and – even if we’re a bit late on this – we make a Christmas Lamp, capable of emitting light of the same color of the surface it is laid on! The project can be divided into three “modules”. A “sensor module” able to recognize the color tone of the…
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…
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….
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.
