Design of Flashlight with Adjustable Brightness Based on 51 MCU External Interrupt
This paper introduces the structure of 51 MCU interrupt system,designs the hardware circuit and control program of the luminance adjustable flashlight based on 51 MCU external interrupt,and uses Keil C51 and Proteus software to simulate the hardware circuit and control program.The results show that the brightness adjustable flashlight circuit based on external interrupt of MCU can meet the control requirements.
