thoughts on arduinos in PHY100L/200L labs

• Students should be left to focus on the physics, with only some awareness about the arduino and its function as a tool -- not too much (or any?) programming, and minimize technical bugs if at all possible.
• Technical issue minimization:


• possible to load routines onto multiple arduinos at once?
•  possible to load several routines onto a single arduino?  Maybe we can work-around by measuring from several channels simultaneously, and if there is a LO/HI signal then that channel is ignored in outputting to the computer...  Need to check memory requirements to estimate the size of program that is realistic on an Arduino (gut: it should work fine for having 3-5 functions, such as: send/receive audio clicks at regular intervals (~20 ms), receive IR sensor info at regular intervals (for pulley black/white or for sensor of pendulum slipping by).
