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.

Real-time clock made by STC90C54RD+SD2405ALPI

I have an SD2405ALPI-G on hand, and I happen to have an STC learning board, so I made a clock with an annual error of about 2.5 minutes to play with. The schematic and program are all there. Now the hardware has a ringtone generating chip and a power amplifier chip, but the program has only initially implemented the function of displaying the day of the week, hours, minutes and seconds. It will be changed to an alarm clock when there is time.
