Theremino is an Open Source system, to interface the computer with the outside world. There are examples, from the simplest to the most complex scientific applications. You can measure physical quantities of each type, temperature, radiation, magnetic fields, earthquakes, pollution ... and drive actuators, motors, LEDs and lamps, ovens, solenoid valves, relays, robots etc ...
Unlike similar systems (eg Arduino), the system works just turned on, and does not require programming the firmware.
The system Theremino is also a container for the exchange of ideas, including electronics hobbyists. As well as a catalog of sensors and actuators, a teaching aid and a collection of technologies for the Input-Output.
Purpose and philosophy of the system Theremino are teaching and collaboration, the goal is not to sell, but learn how to design. Employees only deal with research and collectively contribute to the improvement of the system. The results are shared and must remain free, as specified in this page

Theremino is similar (or compatible) with Arduino?
No, they are two very different systems.
Arduino is a "Single board micro-controller" that must be programmed, from time to time, with a bespoke firmware. If, for example, you want to read a temperature, then you program the firmware to do this, if the temperatures are two, you change and reprogram the firmware, to read two. Theremino is a "device input-output" as a mouse or a printer. By connecting the modular units, works immediately, without having to program its firmware.
Arduino communicates via USB, but transforms it into virtual serial 9600 baud, upgradeable to 38 Kilo baud, beyond which risk communication errors (and up to 115 Kbaud with programming techniques more difficult). Theremino communicates via USB native, fixed speed of 12 Mega baud.
It is therefore advisable to use Arduino when you want a plate that does everything by itself, without a PC. We recommend instead Theremino when you want to use the PC as "head" thinking and you have to quickly communicate with the hardware. For example you can acquire 48 channels, 500 times per second, while doing the log and also display ( downloads / geology # dolfrang ).

They are all similar to each other, a micro-controller mounted on a printed circuit board, with around some connectors for input / output. There are already many, because they propose a much more?
The best explanation was given by Stephen, a maker, who wrote: Clearly it always starts from Arduino, but soon I realized its limitations: it is a small computer with I / O that is programmed, but I want a BIG computer to add I / O!
What makes possible the operation "NO CODE"
Operation type PLC (programmable logic controller)
Since the "head" is the PC the most appropriate technical term is "Soft PLC".
The application HAL (Hardware Abstraction Layer) refreshes all inputs and outputs at regular intervals (usually 500 times per second) and normalizes the data, simplifying communication with the hardware.

Communication between the modules, through the slot
The Slot (interprocess communication) are the basis of the system Theremino and differentiate it from all similar systems. Slot with not only the hardware modules but also the applications can communicate with each other.
Software and sign configurable and expandable in Open Source
Applications, available in open source, covering all common operations, from multimedia, as measured by the laboratory. New applications can be developed from Open Source code of the existing ones, as new bricks, to expand the possibilities of the system.
Modular hardware and software
Although applications can be added as modules, multiple applications can be configured to communicate with each other, and work together, without reprogramming.
The modularity of the software is a new concept. No system, until now, has never used the communication and modularity as the system Theremino.
In Theremino system, each application is responsible only for its specific features, and most applications work together to achieve the desired result. This allows to build complex systems, with simple brick.
With Theremino do not need to be experienced programmers, to realize their ideas. Also artists, chemists, musicians, geologists, climatologists and students, can build what they need, combining the existing hardware and software modules.
The "Pin" of the system can be configured individually, with a large number of pre-programmed functions, which cover every need of Input-Output.
You can connect sensors and assign new functions to the pins of In-Out, even during operation. You can add modules, and set them up in a few seconds. The modules are automatically recognized, and communicate with each other through a single-wire serial line. Each line supports up to 200 modules and each module ten Pin. The total number of InOut is virtually unlimited, and they can communicate with each other, or with other applications via HAL (Hardware Abstraction Layer) and Slots (interprocess communication). The modules can communicate with each other, up from miles away, on a serial line, at great distances on wires and on the web. The usable operating systems are Windows, Unix, Linux, Mac OSX and Android.
The simplicity, small size and low cost of the modules, do not reduce performance, quite the contrary. The simplicity makes the system very robust, and performance are such as to refresh all InOut simultaneously, so fluid (up to 500..1000 times per second).
Getting the system modules
The team system Theremino deals only with research and does not sell hardware. The system is completely "Freeware", "Open Source", "No Profit" and "DIY", but there are manufacturers who can deliver the modules assembled and tested at a great price. One could hardly self-build them spending less. A list of manufacturers in this page: www.theremino.com/contacts/producers
