Access Arduino I/O pins via serial commands with Softboard
Enthusiast Robert Epprecht has created an interesting software tool for an Arduino - a serial-based command line system that allows interrogating I/O pin status with simple text commands. Thus the Arduino can act as a real-time interface between sensors (etc) and your PC via the serial monitor. This can be useful when you want to quickly read values without writing a sketch. For example, if you want to monitor the value measured by analogue pin 3, you would enter "A3 v" into the command line, and the results would appear similar to the following:
There are many other options, so visit Robert's github page for the sketch and more information. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
