【Altlink】Intelligent four-way switch based on Altlink zero code

Introduction to the intelligent four-way switch project based on Yatelian
:
This is an intelligent four-way switch based on Yatelian CB3S module and developed using Yatelian zero-code platform. The switch control is realized through the onboard button open source, and the four-way switch can be controlled by the mobile phone, and the control types are rich.
Functions and market application prospects of the project:
It is suitable for switches and other equipment, with random timing, cycle timing, inching switch (delayed closing), and ordinary relays to realize 4-way switch functions. Users can remotely control the switch through the networking configuration of the module. In daily life, the remote start and shutdown of home appliances can be realized through the device, and the control of equipment can also be realized in industrial production. In agricultural production, it can be matched with other sensor modules to realize automatic control of water pumps and other equipment.
In the era of the Internet of Everything, the intelligent switch system has broad market prospects and commercial value. The work has rich practical value in real life.
Software development:
Through 5 steps of development and design in the platform, code firmware can be generated. Orders can be placed through the Lichuang Mall, eliminating the need for code burning, which greatly improves the efficiency of product development.
Hardware development:
After the platform development is completed, the platform will provide a recommended circuit schematic diagram based on the selected equipment and functions. Based on the schematic diagram, the PCB design is completed using EasyEDA (Professional Edition), and one-click PCB proofing and component purchase are achieved through the client, which is very convenient and fast.
The product can be powered by the Type-C interface or by a terminal block. The DC voltage should be less than 12V and greater than 6V. The product contains two DC linear step-down circuits, one for stepping down 3.3V to power the main control chip, and the other for 5V to power the relay module.
