dimming principle is to use the principle of two modules brightness changes for pwm.   Mercury switches provide a digital signal that triggers the PWM , through the program design,   We can see the light like two cups filled with the effect of shuffling back and forth.
   test code:
   int LedPinA = 5;
   int LedPinB = 6;
   int ButtonPinA = 7;
   int ButtonPinB = 4;
   int buttonStateA = 0;
   int buttonStateB = 0;
   int brightness = 0;
   void setup()
   pinMode(LedPinA, OUTPUT);
   pinMode(LedPinB, OUTPUT);
   pinMode(ButtonPinA, INPUT);
   pinMode(ButtonPinB, INPUT);
   void loop()
   buttonStateA = digitalRead(ButtonPinA);
   if (buttonStateA == HIGH && brightness != 255)
   brightness ++;
   buttonStateB = digitalRead(ButtonPinB);
   if (buttonStateB == HIGH && brightness != 0)
   brighness --;
   analogWrite(LedPinA, brightness); //
   analogWrite(LedPinB, 255 - brightness); //
