Scheme description:

The solution uses the HS16F3211 touch chip.Achieve touch part of the function:Two touch pins are used to control two ports to output the control signal;The touch sensitivity of the chip can be adjusted by software according to the environment to adapt to different application scenarios, and the control signals output by the port can also be controlled by programming according to different needs.

Function description:

Key sequence：OFF -Induction ON/Induction/OFF→ OFF - Cyclic power-on enters OFF by default

Key sequence：ONOFF-Turn on the light of the bath mirror-MODE Touch the button-Adjust the cold and warm lighting-ONOFF- Close
