多個在不同時間

Question

我試圖把在三個不同的LED，但我希望他們關閉在不同的時間，但這個看起來不可能的LED ....：哭： 這裏是我的代碼：

import RPi.GPIO as GPIO 
import time from threading 
import Thread 
def led1(): 
GPIO.setmode(GPIO.BOARD) 
GPIO.setup(36, GPIO.OUT) 
GPIO.output(36,1) 
time.sleep(3) 
GPIO.output(36,0) 
GPIO.setwarnings(False) 
def led2(): GPIO.setmode(GPIO.BOARD) 
GPIO.setup(38, GPIO.OUT) 
GPIO.output(38,1) 
time.sleep(5) 
GPIO.output(38,0) 
GPIO.setwarnings(False) 
def led3(): 
GPIO.setmode(GPIO.BOARD) 
GPIO.setup(40, GPIO.OUT) 
GPIO.output(40,1) 
time.sleep(7) 
GPIO.output(40,0) 
GPIO.setwarnings(False) 
thread1= Thread(target = led1) 
thread2= Thread(target = led2) 
thread3= Thread(target = led3) 
thread1.run() thread2.run() 
thread3.run() 
##thread1.join() // not sure if I have to put that or not 
##thread2.join() 
##thread3.join() 
GPIO.cleanup() 

Answer 1

爲什麼不做這樣的事情？

import RPi.GPIO as GPIO 
import time 

GPIO.setmode(GPIO.BOARD) 
GPIO.setup(36, GPIO.OUT) 
GPIO.setup(38, GPIO.OUT) 
GPIO.setup(40, GPIO.OUT) 
GPIO.setwarnings(False) 

GPIO.output(36,1) 
GPIO.output(38,1) 
GPIO.output(40,1) 

time.sleep(3) 
GPIO.output(36,0) 
time.sleep(2) 
GPIO.output(38,0) 
time.sleep(2) 
GPIO.output(40,0) 

GPIO.cleanup() 

編輯：如果你不知道的時候每個LED將是對：

import RPi.GPIO as GPIO 
import time 

GPIO.setmode(GPIO.BOARD) 
GPIO.setup(36, GPIO.OUT) 
GPIO.setup(38, GPIO.OUT) 
GPIO.setup(40, GPIO.OUT) 
GPIO.setwarnings(False) 

led1time = 3 
led2time = 5 
led3time = 7 
m = max(led1time, led2time, led3time) 

GPIO.output(36,1) 
GPIO.output(38,1) 
GPIO.output(40,1) 

t = 0 
while t <= m: 
    if t >= led1time: 
     GPIO.output(36,0) 
    if t >= led2time: 
     GPIO.output(38,0) 
    if t >= led3time: 
     GPIO.output(40,0) 
    time.sleep(0.1) 
    t += 0.1 

GPIO.cleanup() 

您現在可以設置每個LED多久會在與0.1秒準確性，你可以通過用較低的數字替換任何出現的0.1來提高精度。
