8. Read Distance¶
Through the Ultrasonic Module in its head, PiDog can detect obstacles ahead.
An ultrasonic module can detect objects between 2 and 400 cm away.
With the following function, you can read the distance as a floating point number.
Pidog.ultrasonic.read_distance()
Here is an example of usage:
from pidog import Pidog
import time
my_dog = Pidog()
while True:
distance = my_dog.ultrasonic.read_distance()
distance = round(distance,2)
print(f"Distance: {distance} cm")
time.sleep(0.5)
