Product description
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); //
delay(25);
