Theremino is an Open Source system and teaching, to easily interface the PC with the outside world. There are many examples, from simple (light a led), to complex scientific applications (gamma spectrometry). Can be measured, with cheap sensors, each type of physical quantity, temperature, radiation, magnetic fields to chemical compounds. And you can control servos, motors, LEDs and lamps, ovens, solenoid valves, relays, process controls, robots, etc.
Unlike similar systems (eg Arduino), the system works just turned on and does not require programming the firmware.
This site describes the modules of the system Theremino, and is also a useful catalog of sensors and actuators, a teaching aid and a binder for the best ideas and technologies Input Output for PC.

The purpose and philosophy of the system Theremino are teaching and collaboration, the goal is not to sell, but learn how to design. The employees work only search and collectively contribute to the improvement of the system. The results are shared and you want it to 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, one wants to read a temperature, then the firmware program to do so, if the temperatures are two, is modified and reprogramming the firmware, to read two. Theremino is an "input-output device", such as a mouse or a printer. By connecting the modular units, it works immediately, without reprogramming the firmware every time.
Arduino communicates via USB, but turns it into a virtual serial at 9600 baud, which can be increased up to 38 Kilo baud, beyond which the risk of communication errors. (And up to 115 Kbps with programming techniques more difficult). Theremino communicates via USB natively, fixed speed of 12 Mega baud.
It is therefore advisable to use Arduino when you want a plate that does it all by itself, without PC. Instead, we recommend Theremino when you want to use the PC as a "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 the view ( 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. Many have already, why propose yet another?
The best explanation was given by Stephen, a maker, who wrote: Of course it always starts from the Arduino, but I soon realized its limitations: it is a small computer with I / O that must be programmed, and I want a LARGE computer to add the 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) cools all the inputs and outputs at regular intervals (typically 500 times per second) and normalizes the data, simplifying the 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. With Slot not only modules but also hardware applications can communicate with each other.
Software and sign configurable and expandable in Open Source
Applications are 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 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 collaborate, 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 the system Theremino each application is concerned only with its specific functions and more applications collaborate to achieve the desired result. This allows you to build complex systems with simple brick.
With Theremino do not need to be experienced programmers to implement their ideas. Also artists, chemists, musicians, geologists, climatologists and students can build what they need, by combining existing software and hardware modules.
The "Pin" of the system are individually configurable, with a large number of pre-programmed functions that cover every need of Input-Output.
You can connect sensors and assign new functions to pin In-Out, even during operation. You can add modules and redo the configuration in a few seconds. The modules are automatically recognized and communicate with each other through a fast serial line single-wire. Each line supports up to 200 modules, and each module a dozen 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), up from miles away on the serial line, at large distances of network cables and on the web, and with every Windows operating system, Unix, Linux, Mac OSX and Android.
The simplicity, small size and low cost of the modules does not affect the performance, in fact the opposite is true. The simplicity makes the system very robust and the performance is such that they can refurbish all InOut simultaneously up to 500 times per second.
Get the system modules
The team Theremino system is only concerned with research and does not sell hardware. The system is completely "Freeware", "Open Source", "No Profit" and "DIY", but there are manufacturers who can provide modules assembled and tested at a great price. One could hardly self-build them for less money. A list of producers on this page: www.theremino.com/contacts/producers
