I dont know whats wrong heres my code:
/************************************************
- name:Ultrasonic
- function: if you use a piece of paper to approach or keep it far away from the sensor.
- You will see the value displayed on the LCD changes,
- which indicates the distance between the paper and the ultrasonic sensor.
