Smart lights and fans

Overview

Control the relay through voice control of the pins of the VC-02 module to achieve the required functions. It can be plugged into a 3.7V lithium battery for power supply, or it can be plugged into USB for power supply. When both are plugged in, the lithium battery will be charged while powering. Two booster chips are used to boost the voltage to 5V and 12V. When powered by a lithium battery, it needs to be raised to 5V to provide stable power supply to VC-02. Small lights and fans require 12V to work properly.

The fan speed adjustment uses PWM, so the relay is always changing direction, so there will be a beeping sound. When the fan is turned on to the 3rd gear and the high level duty cycle is 100%, there will be no There was a sound.
