Zi millionstate of flowing water lamp can give a person one kinds visual impact. Intends to adopt AT89C51 microcontroller to go achieve such kaleidoscopic of flowing water lights. MCU technology is a kind of tradition and typical technical, with intelligent, the volume is small, high integration and price inexpensive and so on many unique advantages. Moreover singlechip obviously superior to other electronic circuit, its hardware circuits and software aspects of are not particularly plicated. The singlechip design will bine theory and practice, the main use AT89C51 singlechip design of a musical water lights. First, design a stable DC power supply circuit, and then design a reset circuit for the microcontroller to provide normal working conditions, and then design a clock circuit and sound driver circuit, will enable MCU to better control and pile music part, in addition to design a to facilitate munication circuit chip and PC connectivity and munication, and finally also need to design the circuit to control the music keys light water. In order to make the buzzer to normal design an audio circuit needs to happen. After the hardware circuit design to connect the modules for simulation and debugging. Software design will need to be piled each circuit module, and the design frequency of the music program, water lights and key procedures, and its bination of simulation debugging and debugging. When playing music in order to achieve a kaleidoscopic effect LED lights to meet the visual enjoyment.
