灯光控制，调光台灯，使用pic12f509，实现pwm输出进行量度控制。-Light control, lamp dimmer, use pic12f509, make measurement in the realization of control pwm output.

假设现在有个产品，要实现一个按键调节LED的亮度（PWM六档调光）。要以最低成平，体积要小,抗干扰最好。用PIC12C508A，最适合不过了。-Assume now that a product, brightness to achieve a key regulator of LED (PWM six files dimming). At the lowest level, small size, the best anti interference. With the PIC12C508A,
