Fix Serial SimpleWrite example

gohai · gohai · commit 61fe120f7c22 · 2015-10-18T12:29:14.000+02:00
The Arduino code would read one byte from the buffer an then sleep for 1/10th of a second, while Processing would send a byte every frame. Instead, read in all the bytes in the input buffer and act on the most recent one.
