Microcontroller replacement project

 
Overview

Divided into basic parts, the digital tube displays 3 channel values. The upper and lower limits of the value are modified through the serial port and an audible and visual alarm is triggered when the upper and lower limit values ​​are exceeded. The expansion part LCD1602 displays the DS18B20 value and transmits the data to the mobile app through Bluetooth (I'm so stupid, I don't have 5v power on the board, so Bluetooth can't be used)
