The Arduino compatible Light Cup Module is a set of two boards which has LED and a mercury tilt switch. This module is based on the principle of PWM dimming; you can achieve the brightness of two LEDs changes as they are tilted, as the light is magically moved from one module to the other. Two components combined, a mercury tilt switch and a LED. When you tilt the mercury switch, the led will turn on and off.

This Light Cup Module operates on a 5V DC supply. Compatible with Arduino-compatible boards.

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) {
brightness -;
}

analogWrite(LedPinA, brightness);
analogWrite(LedPinB, 255 - brightness);
delay(25);
}
