SunFounder PiDog Kit, Release 1.0
After running this example, PiDog’s ultrasonic module will detect whether there is an obstacle ahead, If it detects your
hand, it makes the breathing light glow red, takes a step back, and barks.
At the same time, the touch sensor will also work. If the touch sensor is stroked (not just touched), PiDog will shake
its head, wag its tail, and show a comfortable look.
