while True:

        INA.value(0)
        INB.value(1)

Explanations

Conceive:

1. Initialization:

   Set pins of the capacitive touch sensor and the 130 motor.

   Define a variable press with an initial value of 0, which is used to control the state of motor.

2. Loop:

   if touch.value() == 1 and press == 0: 
       INA.value(0)
       INB.value(1)
       press = 1
   

   When the module is touched (touch.value() == 1) and press = 0, the fan rotates and press will be assigned to value 1.

   elif touch.value() == 1 and press == 1:
       INA.value(0)
       INB.value(0)
       press = 0
   

   When the module is touched (touch.value() == 1) and press = 1, the fan stops working and press will be assigned to value 0.

   Point: When we continuously touch the module, we need to know and control the state of the motor through the value of press.
