DIY的3W LED手电程序，5 个模式，三个PWM亮度等级，二级闪烁模式，用的是PIC12F629-The 3W LED Flashlight DIY process, five models, three PWM brightness levels, two flashing modes, using a PIC12F629

PWM控制灯亮，主要使用的一些手电平台，或者简单的照明装置(PWM control the light on,Some of the main flashlight platforms, or simple lighting fixtures)

本程序使用AVR系列单片机ATmega88来控制LED的各种功能，通过单按键可以实现LED灯光的关断、弱光、强光、SOS光源等效果，再关断光源的同时，电路即进入睡眠状态，有效的保证低功耗的实现。(The various functions of this program uses the AVR Series MCU ATmega88 to control LED, the single button can achieve LED lights off, weak light, light,

LED手电多段恒流控制包涵 电路图、应用方块图、PCB及零件表等数据(LED multi section constant current control inclusion circuit diagram, application block diagram, PCB and part table data)
