Project 9: Avoiding obstacles
Overview
Why some intelligent robots can automatically avoid an obstacle ahead?
Easily, use an obstacle avoidance sensor. In this project, we’ll simply test
the obstacle avoidance sensor.
Component Required:
 EASY plug control board*1
 EASY plug obstacle detector sensor *1
 EASY plug LED module *1
 EASY plug motor *1
 RJ11 cable *2
 USB cable*1
Component Introduction:
EASY plug Obstacle Avoidance Sensor
Infrared obstacle avoidance sensor is
equipped with distance adjustment function
and is especially designed for wheeled
robots.
This sensor has strong adaptability to
ambient light and is of high precision. It has
a pair of infrared transmitting and receiving tube.
When infrared ray launched by the transmitting tube encounters an
obstacle (its reflector), the infrared ray is reflected to the receiving tube,
after a comparator circuit processing, the indicator will light up.
You can adjust the detection distance by rotating the potentiometer knob,
