13 Bit-banging driver using two GPIOs:
14 - trigger-gpio is raised by the driver to start sending out an ultrasonic
16 - echo-gpio is held high by the sensor after sending ultrasonic burst

13 Bit-banging driver using one GPIO:
14 - ping-gpios is raised by the driver to start measurement
15 - direction of ping-gpio is then switched into input with an interrupt
