## "School-Level Electronic Design Competition" Design Summary Report

Title: Multi-rotor Basic requirements for autonomous aircraft (question G)

(3): Make a simple electronic altitude display device.
This module uses a 3.7V lithium battery to power the laser. It is boosted to 6V by a boost circuit to power the laser, and then stabilized to 3.3V to power the chip and other circuits. The module uses the STM32F103C8T6 chip and uses 3 LED indicators, namely the power indicator light: it is always on when the power supply is normal, the work indicator light: it flashes when the program is running normally, and the laser alarm indicator light: it turns on when the aircraft is detected. Using the buzzer module, it will sound when the aircraft is detected. The laser adopts npn normally open type, 6V power supply, default low level. After detecting the aircraft, it outputs 6V high level. After the resistor divides the voltage, it is input to the IO port to detect the rising edge interrupt. Take appropriate action.
