        rgb[2] = (255,255,0)
        rgb.write()
    elif(touchPad_O.read() < 100):
        rgb[0] = (255,0,255) #关灯
        rgb[1] = (255,0,255)
        rgb[2] = (255,0,255)
        rgb.write()
    elif(touchPad_N.read() < 100):
        rgb[0] = (0,255,255) #关灯
        rgb[1] = (0,255,255)
        rgb[2] = (0,255,255)
        rgb.write()

First, import the mPython module, Try to touch the P gold finger with your finger and use read() to read the value. Observe the changes:

>>> from mpython import *
>>> touchPad_P.read()
643
>>> touchPad_P.read()
8

Note

The control board has 6 touch pads on it, touchPad_P、touchPad_Y、touchPad_T、touchPad_H、touchPad_O、touchPad_N，from left to right, and other touch keys are used as above.
