   Autonomous Arduino 101 based 4WD Rover code.
   This code drives an Arduino101 microcontroller board
   using the builtin Bluetooth Low Energy (BLE) functonality
   , 4 sets of motor on the SEEDstudio Skeleton Bot chassis
   driven by 2 grove I2C motor control drivers.
   Additional components included from SEEDstudio include:
   Grove LED Socket, Green LED, Grove 80cm proximity sensor

/*
  digital input, digital output, serial output

 Reads an analog input pin, maps the result to a range from 0 to 255
 and uses the result to set the pulsewidth modulation (PWM) of an output pin.
 Also prints the results to the serial monitor.

 The circuit:
 * potentiometer connected to analog pin 0.
   Center pin of the potentiometer goes to the analog pin.
