An Arduino sketch used to test the S-Expr repo, which implements very simple S-Exprs for serial communications.
I don't know of a good way to do automated, X-Unit style testing on an Arduino. I simply call my test functions and print "RED" or "GREEN".
Certainly, these tests are valuable as an example of how to use the code.
This is a very early version of this code. If people find it valuable, it cannot no doubt be greatly improved.
