AT series of music-based Lantern Controller MCU

Abstract

Author : TingWu Tutor :HuaZhen wang

The design is based on SCM'S music lights control system. It consists of hardware and software components. In which the hardware from the power supply circuit, acceleration and deceleration button, single-chip small systems, LED display circuit has four major components. The system design is a new type of LED lights in the control system design methodology to AT89C52 microcontroller as the core and the power supply circuit LED display circuit combines the use of software control of the LED lights. The system has small size, less hardware, the circuit structure is simple and low cost advantages.

Key words: AT89C52 microcontroller; LED Lantern; process control
