PWM control of LED lights getting brighter gradually eliminate procedures apply ME300B development system oscillator for 11.0592M the use of timer control which produces a variable duty cycle PWM wave by K1, PWM value is increased, then the duty cycle decreases, LED lights dimming. According to K2, PWM value is reduced, then the duty cycle increases, LED lights gradually brighter. When the PWM value is increased to maximum or reduced to minimum, the buzzer will alarm.
