 * 
 * LINEAR ACTUATOR & FLIPPER PROGRAM CONTROL!


further modified 19 May 2016, Thayer ENGS21 proj, Wes Kendrick.
Using grove shield, 


modified even more for the linear actuator 5/25/2016

CONFIG!!!
servo wired to D7
switch to D5

//potentiometer is wired into A0. Note that the cable, as it is currently configured, is screwed up, need jumper cables
//brown == ground; red = power, orange == signal.
