Question

我的项目有两个部分存在问题。我正在使用覆盆子pi来读取和控制电位计和一些LED。

1当我用电位器控制LED时，我的LED闪烁在我的低阈值但不在我的高电平上，我该如何解决这个问题？

（固定）2当我第一次启动脚本时，我的电位器必须设置为0另外我从电位器获取异常读数，我该如何解决？

我尝试过前后添加延迟。我之前尝试过添加中心字符串而没有运气。我在谷歌搜索解决方案没有运气。我找到的只是眨眼例子的脚本。

我通过python在我的覆盆子pi上运行这个脚本来控制我的arduino。如果我将它贴在错误的区域，请告诉我应该在哪里发布，以便我可以移动它。

这是我的剧本！

from nanpy import Arduino
from nanpy import serial_manager
from time import sleep

serial_manager.connect('/dev/ttyUSB0')

POT = 0
LED1 = 13
LED2 = 12
LED3 = 11
LED4 = 10
LED5 = 9
LED6 = 8
LED7 = 7
LED8 = 6

Arduino.pinMode(10, Arduino.OUTPUT)
Arduino.pinMode(9, Arduino.OUTPUT)
Arduino.pinMode(8, Arduino.OUTPUT)
Arduino.pinMode(7, Arduino.OUTPUT)
Arduino.pinMode(6, Arduino.OUTPUT)

print "starting"
while True:
    pot = Arduino.analogRead(POT)
#this is the section that is blinking when it shouldn't

Answer 1

我在初始化时看到了一个问题：

POT = Arduino.analogRead(0)

然后，在此期间，您在此处使用POT作为密码，但POT将在上面的行中初始化为变量：

pot = Arduino.analogRead(POT)

我认为这就是你出乎意料的行为的原因。我认为如果你将POT的初始化更改为POT=0或者你的底池连接的引脚号（如果它不是引脚0），它可能会有用。

Answer 2

I figured it out. The blink issue was not expected. However it was acting like the leds were set to an off delay for about .5 seconds. Here is my new script.

from nanpy import Arduino
from nanpy import serial_manager
from time import sleep

serial_manager.connect('/dev/ttyUSB0')

POT = 0
LED1 = 13
LED2 = 12
LED3 = 11
LED4 = 10
LED5 = 9
LED6 = 8
LED7 = 7
LED8 = 6

Arduino.pinMode(POT, Arduino.INPUT)
Arduino.pinMode(13, Arduino.OUTPUT)
Arduino.pinMode(12, Arduino.OUTPUT)
Arduino.pinMode(11, Arduino.OUTPUT)
Arduino.pinMode(10, Arduino.OUTPUT)
Arduino.pinMode(9, Arduino.OUTPUT)
Arduino.pinMode(8, Arduino.OUTPUT)
Arduino.pinMode(7, Arduino.OUTPUT)
Arduino.pinMode(6, Arduino.OUTPUT)

print "starting"
while True:
    pot = Arduino.analogRead(POT)
    if pot < 450:
        Arduino.digitalWrite(LED1, Arduino.HIGH)
        Arduino.digitalWrite(LED2, Arduino.HIGH)
        Arduino.digitalWrite(LED3, Arduino.HIGH)
        Arduino.digitalWrite(LED4, Arduino.HIGH)
        Arduino.digitalWrite(LED5, Arduino.LOW)
        Arduino.digitalWrite(LED6, Arduino.LOW)
        Arduino.digitalWrite(LED7, Arduino.LOW)
        Arduino.digitalWrite(LED8, Arduino.LOW)
        sleep(.01)
    elif pot > 650:
        Arduino.digitalWrite(LED1, Arduino.LOW)
        Arduino.digitalWrite(LED2, Arduino.LOW)
        Arduino.digitalWrite(LED3, Arduino.LOW)
        Arduino.digitalWrite(LED4, Arduino.LOW)
        Arduino.digitalWrite(LED5, Arduino.HIGH)
        Arduino.digitalWrite(LED6, Arduino.HIGH)
        Arduino.digitalWrite(LED7, Arduino.HIGH)
        Arduino.digitalWrite(LED8, Arduino.HIGH)
        sleep(.01)
    else:
        Arduino.digitalWrite(LED1, Arduino.LOW)
        Arduino.digitalWrite(LED2, Arduino.LOW)
        Arduino.digitalWrite(LED3, Arduino.LOW)
        Arduino.digitalWrite(LED4, Arduino.LOW)
        Arduino.digitalWrite(LED5, Arduino.LOW)
        Arduino.digitalWrite(LED6, Arduino.LOW)
        Arduino.digitalWrite(LED7, Arduino.LOW)
        Arduino.digitalWrite(LED8, Arduino.LOW)
        sleep(.01)
    print pot

arduino引发的问题由raspberry pi / python控制
