two-way communication, but it relies on executing commands which are not going
to take a whole lot of time or add any delays to each loop.
+The example includes the following files:
+README.txt --- This file.
+LICENSE.txt --- The license governing distribution and modification of this
+python-ui.py --- A graphical user interface written in python which uses
+ Tkinter. Note that this program requires that the pySerial
+ extension be installed. PySerial can be downloaded at
+ http://pypi.python.org/pypi/pyserial .
+comm_example/comm_example.pde --- The example Arduino sketch. This program
+ Flashes an LED on for a second and off for a second, then
+ repeats. During this time it sends a signal over the serial
+ line indicating how many times the LED has been on, every 10
+ flashes. It also responds to inquiries about the current
+ state of the LED and the connection.
Basically every time the Arduino runs through loop I do two things:
1. Monitor and or change any I/O pins that require monitoring or changing.
