Use an old PC as Arduino

[v205]

If you just want to compute serial data take a look at this:
Note: those programs were designed on Linux may need to change things a bit….

Demo of PC-Arduino comms using Python

I haven't been able to find a piece of example code (both the Python and the Arduino stuff) that can reliably send and receive text and/or binary data between a PC and an Arduino. So I have written a pair of demo programs - one in Python and one for the Arduino - in the hope that they might be useful to newcomers. I have written the programs on a Linux PC. It would be great if someone could let me know if they work on Windows and Mac systems. I originally wrote the Python program in JRuby as I…

Demo of PC-Arduino comms using Python

I thought it may be useful to produce a slightly simpler version of the Python - Arduino example which only uses printable characters. That means that the Arduino program can be worked from the Serial Monitor as well as with the Python program. The new version also contains elements of the code from this Thread to illustrate how to parse the data and use it to control LEDs and a servo. The Arduino code assumes there are LEDS connected to pins 12 an 13 and a servo connected to pin 8. If you se…

Serial Input Basics - updated

Updated Version Please note that this is a revised version of the advice in this earlier Thread which has become very long. As far as possible I have kept the code examples identical or simplifed them slightly. It should not be necessary to refer to the older Thread, but feel free to do so. Contents The following sections are in this Tutorial Introduction Serial data is slow by Arduino standards Example 1 - Receiving single characters Why code is organized into functions Exampl…
