1. 快速利用树莓派创建智能硬件的网站：http://www.smartpi.cn/#/SdkVersionList

2. Win-SCP可以把写好的程序导入树莓派的板子（记得提前与树莓派连接同一个wifi）

3. RGB LED三色灯的程序（书52页）经过漫长debug后终于成功运行，主要的问题有：小括号中括号不分，大小写不分，缺失关键语句等等。运行的语句为：python RGB-yc.py。最终成功的程序如下：
*Python版本
 import RPi.GPIO as GPIO

     global pins

     pins = {'pin_R':Rpin, 'pin_G':Gpin,'pin_B':Bpin}
     GPIO.setmode(GPIO.BOARD)

     p_G.start(0)
     p_B.start(0)
 def makerobo_pwm_map(x, in_min, in_max, out_min, out_max):
     return (x-in_min)*(out_max - out_min) / (in_max -in_min) + out_min
 def makerobo_off():

     G_val = (col & 0x00ff00) >> 8
     B_val = (col & 0x0000ff) >> 0
     R_val = makerobo_pwm_map (R_val, 0, 255, 0, 100)

     p_G.ChangeDutyCycle(100-G_val)
     p_B.ChangeDutyCycle(100-B_val)
 def makerobo_loop():
     while True:
         for col in colors:
             makerobo_set_Color(col)
             time.sleep(1)
 def makerobo_destoy():
     p_R.stop()
     p_G.stop()
     p_B.stop()
     makerobo_off()
     GPIO.cleanup()
 if __name__ == "__main__":
     try:
         makerobo_setup(makerobo_R, makerobo_G, makerobo_B)
         makerobo_loop()
     except KeyboardInterrupt:
         makerobo_destroy()

4. 智能台灯：在网站上设计后把SDK文件下载解压，烧入智能台灯的语音识别板块。以下文件需要先导入树莓派才能正常使用：
*Python版本的程序
 import RPi.GPIO as GPIO
 import time
 GPIO.setmode(GPIO.BCM)
 GPIO.setup(25,GPIO.IN)
 GPIO.setup(26,GPIO.IN)
 GPIO.setup(5,GPIO.OUT)
 GPIO.setup(6,GPIO.OUT)
 while True:
     input1 = GPIO.input(25)
     input2 = GPIO.input(26)
     if(input1 == True):
         GPIO.output(5,GPIO.HIGH)
     else:
         GPIO.output(5,GPIO.LOW)
     if(input2 == True):
         GPIO.output(6,GPIO.HIGH)
     else:
         GPIO.output(6,GPIO.LOW)
