用Python利用pyFirmata控制Arduino實現Blink

2018-03-2809:20:44

arduino中有相應的庫

1.安裝pyFirmata包

    pip install pyFirmata

   在python2.7或python3.X下均可以執行。

   pyFirmata包實現了python對Arduino進行控制的功能，它與Arduino之間通訊遵循的是Firmata協議

   若是pyton下運行from pyfirmata import Arduino不報錯，證實安裝成功

2.在Arduino IDE中爲Arduino寫入程序Standard Firmata.

from pyfirmata import Arduino, util   
import time
board = Arduino('COM8')                #Arduino所在串口是COM8,這是windows下的表示

while 1:
     board.digital[13].write(0)           #向端口13寫入0
     time.sleep(1)
     board.digital[13].write(1)          #向端口13寫入1
     time.sleep(1)

更新：驅動舵機源碼：

from pyfirmata import Arduino, util
import time
board = Arduino('COM3')                #Arduino所在串口是COM8,這是windows下的表示
while 1:
    """
    board.digital[13].write(0)           #向端口13寫入0
     time.sleep(1)
     board.digital[13].write(1)          #向端口13寫入1
     time.sleep(1)
    
    """
    board.servo_config(13,0,255,20)
    print("ceshi")
    time.sleep(1)
    board.servo_config(13, 0, 255, 255)
    time.sleep(1)
