Motorgeschwindigkeit regulieren in Python programmieren

[pinsel120866]

Vielen herzlichen Dank, tucow - nun habe ich es:

import RPi.GPIO as GPIO

import time
import signal

from pizypwm import *

def endProcess(signalnum = None, handler = None):
    first.stop()
    second.stop()
    third.stop()
    fourth.stop()

    GPIO.cleanup()
    exit(0)

signal.signal(signal.SIGTERM, endProcess)
signal.signal(signal.SIGINT, endProcess)

first = PiZyPwm(20000, 19, GPIO.BOARD)
second = PiZyPwm(20000, 21, GPIO.BOARD)
third = PiZyPwm(20000, 23, GPIO.BOARD)
fourth = PiZyPwm(20000, 24, GPIO.BOARD)

GPIO.setwarnings(False)

GPIO.setmode(GPIO.BOARD)

GPIO.setup(19,GPIO.OUT)
GPIO.setup(21,GPIO.OUT)
GPIO.setup(23,GPIO.OUT)
GPIO.setup(24,GPIO.OUT)

while True:
    
    first.start(50)
    second.start(0)
    third.start(50)
    fourth.start(0)
    print "Drehung nach rechts"
    time.sleep(1)

    first.start(0)
    second.start(0)
    third.start(0)
    fourth.start(0)
    print "Stop"
    time.sleep(1)
    
    first.start(0)
    second.start(50)
    third.start(0)
    fourth.start(50)
    print "Drehung nach Links"
    time.sleep(1)

    first.start(0)
    second.start(0)
    third.start(0)
    fourth.start(0)
    print "Stop"
    time.sleep(1)

    first.start(50)
    second.start(0)
    third.start(0)
    fourth.start(50)
    print "Geradeaus vorwaerts"
    time.sleep(1)
    
    first.start(0)
    second.start(0)
    third.start(0)
    fourth.start(0)
    print "Stop"
    time.sleep(1)

    first.start(0)
    second.start(50)
    third.start(50)
    fourth.start(0)
    print "Geradeaus rueckwaerts"
    time.sleep(1)

    first.start(0)
    second.start(0)
    third.start(0)
    fourth.start(0)
    print "Stop"
    time.sleep(1)

Damit drehen die Motoren nur mit 50% Leistung, dank Software - PWM
