Automatic Soymilk Maker Control System Based on STM32

Project Description:
This design uses the STM32F103C8T6 microcontroller as the main control chip, combined with various modules to achieve intelligent operation. The main modules include a sensor module, clock module, display module, motor drive module, and heating module. The sensors mainly include temperature, ultrasonic, and turbidity sensors. The clock module is implemented using a DS1302. The display module uses an OLED screen. The motor drive module uses an MX1508 to drive a DC motor for simulating stirring. Through the combination of these modules, the soymilk maker achieves intelligent operation. The program is programmed using STM32CubeMX and Keil5.
The open-source license is
   GBL 3.0 .
  Project-related functions:
  Pressing the right button enters the system settings interface, mainly for setting the concentration, temperature, and speed. After entering the settings interface, the left button controls the selected object, which will flash. The up and down buttons can be used to add or subtract values ​​from the selected object. Pressing the OK button will execute the settings, thus achieving automation. When the temperature drops below the holding temperature, the PTC starts heating; when the required concentration is reached, the motor stops rotating, and the grinding process ends.
  Project Schedule
  : March 2024 - April 2024: Schematic and PCB design;
  April 2024 - May 2024: Physical debugging and program writing .
  Notes:
  The DS18B20 schematic requires a pull-up resistor at the data transmission end; otherwise, it will not function properly. A
  physical demonstration
video and source code are attached and can be downloaded.
