Magic light cup moduleMagic Light Cup modules are easy to Interactive Technology Division developed a can and ARDUINO interactive modules, PWM dimming principle is to use the principle of two modules brightness changes. Mercury switches provide a digital signal that triggers the PWM regulator, through the program design, We can see the light like two cups filled with the effect of shuffling back and forth.————————————————————–Example 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){brightness -;}analogWrite (LedPinA, brightness); / / A few Guan Yuan (ii)? analogWrite (LedPinB, 255 – brightness); / / B Yuan (ii) a few Bang?
