1. This product is composed of STM32F103C8T6 microcontroller core circuit + digital tube display circuit + button circuit + LED light indicator circuit + buzzer alarm circuit + power circuit.

2. When the floor height is fixed and the elevator running is known, it can accurately know and display the current position of the elevator with a seven-segment digital tube.

3. Through the stepper motor display, after pressing the button from the 1st to the 7th floor, the stepper motor starts to rotate forward. After reaching the top floor, if you press the 7th floor and the 1st floor, go down, and the stepper motor reverses.

4. The number of floors to go to can be manually set. When the elevator reaches the floor, the system can make interruption processing and stop at the floor.

5. When the elevator works in an unsafe state, the system can make corresponding abnormal processing reactions, such as alarm prompts and the switch will be automatically turned off.

6. The core circuit of the single-chip microcomputer of this design has a power-on reset circuit, a button reset circuit and a crystal oscillator circuit.
