==== The graph is a logistic curve because the nylon sheathing limits the expansion of the rubber tube, otherwise the growth would be exponential.
 * PSI || Displacement (cm) ||
 * 30 || .3 ||
 * 35 || .5 ||
 * 40 || .7 ||
 * 45 || 1.5 ||
 * 50 || 2.5 ||
 * 55 || 3 ||
 * 60 || 3.5 ||

Controlling the air muscle with the Arduino. Two buttons on the breadboard control the compression and release of the muscles.
