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.

Bluetooth power amplifier board based on TPA3110

Using TPA3110 digital power amplifier chip, the power can reach 15W, and there are two power interfaces. The Bluetooth part uses bk8000L finished module, which has good performance and affordable price. Supports button playback and pause, track switching, volume adjustment, and also supports external audio line input and microphone input. After testing the finished product, the sound quality is good, the Bluetooth connection is relatively stable, the button functions are normal, the external audio line input is normal, and the microphone calls are normal. A complete AD project file is provided, which can be modified as needed, and the BOM needs to be exported by yourself.
