Run the Code
cd /home/pi/picrawler/examples
sudo python3 avoid.py
After the code runs, PiCrawler will walk forward. If it detects that the distance of the obstacle ahead is less than 10cm,
it will stop and sound a warning, then turn left and stop. If there is no obstacle in the direction after turning left or the
obstacle distance is greater than 10, it will continue to move forward.
