host, to control Arduino hardware, can be written in any language that the 
host system supports, including high level scripting languages such as Tcl.
</p>

<p>
The StandardFirmata project, which is included with the Arduino IDE, 
implements the Firmata protocol. An Arduino can be programmed with 
StandardFirmata, and then controlled from scripts running on a PC, for a quick 
and easy method of controlling hardware. See the
<a href="https://github.com/pdt/tfirmata/tree/master/examples">examples</a>
directory for a range of small but complete examples, including for:

tfirmata is a complete implementation of Firmata, including board capability
querying. As a result tfirmata should work with all boards supported 
by Firmata.
