Here we do is a home massage chair application, when the LCD serial screen is powered on, a start interface will appear. After a short stay, it will jump to a specific interface. This interface is used to set our current time. When setting, a keyboard will pop up. After setting, click OK to enter the massage mode selection interface. Here, I have set three modes: head massage, back massage, and comprehensive mode. In the mode, the massage intensity can be set, the high, middle, and low gears can be set, and the corresponding LED light will be used for intensity indication; the massage times can also be set, after reaching the set number, it will automatically stop; in the comprehensive model, the head and back will be massaged at the same time, and it can be turned off when it is not needed. These actions are through the STONE Touch Screen serial port screen to achieve command transmission.
Modules required for the project
