LEGO Motoren und Sensoren mit Build Hat ansteuern | Raspberry Pi | TMCZ

Here the commands:

$ sudo raspi-config // --> Interface --> P6 --> No --> Yes

===========

$ pip3 install buildhat // --> Software Herunterladen

=========== Motor Ansteuern --> In .py

from buildhat import Motor

motor_a = Motor('A') // Port vom Motor

motor_a.run_for_seconds(5)

=========== Für die Geschwindigkeit

motor_a.run_for_seconds(5, speed=50)

=========== Farbsensor
// Geht auch mit normalen Farbsensor, 
// jedoch dann 'ColorDistanceSensor' mit 'ColorSensor' ersetzen

from buildhat import ColorDistanceSensor

cls = ColorSensor('B') // Hier wieder Port eintragen

cls.on() // Aktiviert den Sensor

print(cls.get_color())

phpMyAdmin + MariaDB

Here is the Code for if_abfrage.py:

from buildhat import Motor, ColorDistanceSensor
import time
m = Motor('A')
c = ColorDistanceSensor('B')
m.run_for_seconds(1)
print("Vorgang startet")
rd = 'red'
yl = 'yellow'
i = 0
for i in range(500):
        time.sleep(5)
        color = c.get_color()
        if color == rd:
                m.run_for_seconds(1)
                print("Farbe" + color + "erkannt")
        elif color == yl:
                print("Vorgang Beendet")
