Description: Have a timer to control the use of variable duty cycle PWM wave by K1, PWM values increase, then decrease the duty cycle, LED lights dimming. By K2, PWM values decrease, then increase the duty cycle, LED lights become bright. When the PWM value to the maximum value or decrease to the minimum value, the buzzer will alarm.
