| 摘 要： | 该系统以16位高速MSP430F169单片机作为控制核心,可以选择以键盘手动控制和根据外界光照强度自动控制两种方式调节流经LED的电流,即可改变其亮度。键盘手动控制方式步进为1mA,可以实现电流增减;自动控制方式以光敏电阻作为光传感器,将外界光强度变化转化为阻值变化,进而实现智能调节LED亮度的功能。

| Abstract: | This system uses 16 high-speed MSP430F169 monolithic integrated circuits as the control core,can choose one way between using keyboard control and flows through LED according to the outside strength of illumination automatic control two way adjustments the electric current,then change its brightness.Keyboard hand control way step-by-steps is 1mA,can realize the electric current to fluctuate;The automatic control way takes the light sensor by the photosensitive resistance,transforms the outside light intensity change as the resistance number change,then realizes the intelligent control LED brightness function. |
