Screen shot of Logisim 2.7.0 Latest release: Logisim 2.7.1 is now available. [ Full announcement and change log ] (21 March 2011) Logisim is an educational tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits.
This article should acquaint you with basic Arduino programming and show you how to write programs that interact with objects in the real world. (A mandatory disclaimer: the last time I really studied electronics was way back in high school, so this article focuses more on the programming aspects, rather than the electronic side of things.) Physical Computing Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been defined in various ways, but the central idea seems to be the same: physical computing is concerned with developing software that interacts with the world beyond the host computer through a combination of hardware and software—it's aware of the world, so to speak. Such awareness makes these applications capable of sensing external events and responding to them in a predefined way.

Si la méthode invoquée est différente de HEAD et le serveur souhaite rendre public la raison pour laquelle il refuse le traitement, il le fera dans l'entité liée à cette réponse.
The Raspberry Pi is a tiny, solid state, and ludicrously cheap hobby ARM based computer designed in the UK (but thanks to insane UK tax laws needs to be built in China ). It has a USB port, video, sound, an Ethernet port, 256MB RAM, and can run 3 distinct flavours of Linux. Ostensibly the device was developed with the aim of getting kids to code, and as someone who grew up with the UK hobby computing scene of the 1980s and cut their programming teeth hacking games together on the ZX Spectrum, this is something I can thoroughly get behind. The blurb from their website:
Ever wanted to make your own techno music, but are tired of the standard midi controller? Well, you could build a harp (of all instruments) out of lasers and then play it by breaking the beams of light. See how it’s done. The harp is connected to the software synthesizer, the TAOS sensor array sits on the floor in its own stand.
This website is dedicaced to low-fi lovers, circuit bender, electronic's alienation and bleep addict! This website show my work around the circuit bending, my music and a new section : how to circuit bend including shematics !!! In society of consumtion, Circuit bending is a life style with activism, hacking boring machine and D.I.Y. It's a fight against aseptic music!
