Fully automatic washing machine design

This article designs a fully automatic washing machine control system with the AT89C51 microcontroller as the core. This system realizes the control of the entire washing process of the washing machine, including the four stages of user program input, washing, dehydration and end alarm. Laundry control system based on AT89C51 microcontroller, the control panel consists of buttons, indicator lights and LCD display. The buttons select the working mode of the washing machine and the start and pause functions. The indicator lights work with the buttons, and the LCD display shows the working mode of the washing machine. The overall circuit module of the washing machine includes four independent keyboards, indicator lights, motor control and LCD display.

GD32E231 incense machine control board

The incense machine control board is based on GD32E231 as the main control, using timers and PWM to control the running time and intensity of the DC pump. The 4-phase 5-wire stepper motor is ideal for lifting and lowering perfume bottle replacement and installation. The display uses the commonly used ST7567 main control 12864 display screen, which can intuitively display the working status of the incense machine.
