Line sensors are included to have more interaction with the robot, while using the line sensors. The robot can serve as an line following robot. This can expent the usability of the robot, and learn how to use multiple sensors in combination wich each other
3 Line sensors are included in the robot. 2 sensors to detect of the robot goes left or right from the line, and 1 sensor to detect if the robot is still on a line.
the following code is an simple example that prints out the value of the sensor.
from gpiozero import LineSensorfrom time import sleepleft_sensor = LineSensor(10)middle_sensor = LineSensor(17)right_sensor= LineSensor(27)while True:left_detect = int(left_sensor.value)middle_detect = int(middle_sensor.value)right_detect = int(right_sensor.value)print(left_detect, middle_sensor, right_detect)
