  Brief

  Massage chair with modern mechanical technology to reproduce the traditional Chinese medicine meridian massage is an important daily health care equipment. The function of the massage chair is to integrate meridian massage of traditional Chinese medicine with modern high-tech means to help users enjoy a comfortable massage, reduce fatigue, and achieve the effect of health care and physical fitness. With the development of single-chip microcomputer intelligent control, a massage chair with STONE touch screen control application is also added.

  What we need to do here is such an application, select different modes through STONE Touch Screen, realize the control of MCU through serial port communication, and then realize the speed and rotation time control of stepping motor by controlling the level of specific IO, so as to realize the massage function of head and back. The system uses the STONE Touch Screen serial port screen, which can be used to do the touch display function. It is very convenient to develop. Only through the serial port can the MCU be controlled.

  It is used in the massage chair, which can easily realize the setting of a massage function and the adjustment of massage strength, so as to achieve the effect of self-cultivation and reduce fatigue.

  Project Overview

  Here we do is a home massage chair application, will STONE TFT After 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.

  The communication functions are as follows:

  The serial port screen of STONE Touch Screen realizes the function of button switching interface;
 The serial port screen of STONE Touch Screen realizes the function of an automatic jump when starting up;
 The serial port screen of STONE Touch Screen realizes time setting;
 The serial port screen of STONE Touch Screen realizes data variable distribution;
 STONE Touch Screen serial port screen realizes serial command communication.
 STONE Touch Screen serial port screen realizes the function of menu bar selection;

  Modules required for the project:

  STONE Touch Screen;
Arduino ESP32;

  ULN2003 Stepper Motor

  Product features

  ULN2003 is a Darlington display with high voltage and high current. It consists of seven Silicon NPN Darlington tubes. Each pair of Darlington of ULN2003 is connected in series with a 2.7K base resistor. Under 5V working voltage, it can be directly connected with the TTL and CMOS circuit, which can directly process the data that needs a standard logic buffer. Here we use the DIP-16 package, 4-phase 5-wire 5V stepping motor.
