# Sixth Lichuang Electric Competition#Intelligent offline voice

1. Introduction to project functions

 An offline voice-controlled three-way output switch designed using Qiyingtailun's speech recognition module CI-C22GS02S can control the on and off of home equipment through voice without a network. It is tentatively planned to control headlights, Night light and fan are three devices. Because it has three independent relay switch outputs, it can be changed to other devices at will. The selected relay contact capacity parameter is 250VAC/10A, which can meet the needs of most household electrical appliances. This project designs the PCB size for the installation space based on the existing wall switch bottom box at home. After welding the PCB, connect the wires, place it in the bottom box, and then cover the switch panel. In addition to voice control, two of the project's outputs also have manual switch controls. Don't ask me why only two of the three outputs have manual switches. I won't tell you because the original panel in my house has two rockers. Board switch! Because it is a rocker switch, the input switch connected to the GPIO port uses double-edge interrupt triggering, so that it can respond no matter which direction it is pressed, so don't use it too much. The two-position rocker switch uses Dupont wire to connect the RX0 and RX1 pins of the module. These two pins need to be defined as input mode.
