Use this parameter data (e.g. pressure) to see how the
harmonics correlate.

For the lab:


The
Arduino

can control other components in the lab


The
Arduino

can control an entire experiment.

Thank you!


My mentors, Markus and Brian, as well as Joe and the rest
of the
Bucksbaum

group for an awesome summer.


DOE and SLAC for this amazing opportunity.


Steve Rock for his dedication to the program.
