  This is a simple servo tester which will comprehensively test the capabilities of almost any modern servo. It has two pushbuttons, CENTRE and SWEEP and a potentiometer which works as follows:
  - CENTRE Does exactly that, centers the servo, afterwards the potentiometer determines position.
  - SWEEP Sweeps the servo back and forth at a rate determined by the potentiometer setting.
  The PIC uses its internal timer to set up a constant frame duration of 20ms and the border=0>
