Arduino Smart car with supersonic (Arduino 自動避障智慧小車)

   Using Arduino & spuersonic to implement the smart car.
 When it is driving and detected some stuff before  30cm distance,it can  brake automatically then
 drive backward a while and randomly change the  rightward or leftward direction.


運用Arduino 和超音波測距感測器實現智慧小車, 在偵測到物體約30cm之前
進行自動剎車,後退,隨機改變左右方向.
