HOW to Make a Manual Control Fan with KidsIOT

In this project, we adopt a capacitive touch sensor and an 130 motor to combine a fan in manual mode. We can control the startup of the fan by the capacitive touch sensor.

1. Initialization

   Set the sensor pin to IO27. Define a variable press with an initial value of 0 to monitor the state of motor.

   

2. Main Code

   Loop:

   • When the module is touched (IO27 reads 1) and press = 0, the fan rotates, and press will be reassigned to 1.

   • When the module is touched (IO27 reads 1) and press = 1, the fan stops, and press will be reassigned to 0.
