Ks0030 keyestudio Magical Light Cup Module

Introduction

Magic light cup module developed by Shenzhen KEYES Robot Co. Ltd is a module able to be interactive with ARDUINO. The principle is based on the principle of PWM dimming; The brightness of two modules change. The mercury switch provides a digital signal and trigger PWM regulation, and then we can see the effect like changing two set of cups full of light through the program design.

Specification

• Supply Voltage: 3.3V to 5V
• Interface: Digital

int LedPinA = 5;
int LedPinB = 6;
int ButtonPinA = 7;
int ButtonPinB = 4;
int buttonStateA = 0;
int buttonStateB = 0;
int brightnessA = 0;
int brightnessB= 255;
void setup()
{
Serial.begin(9600);
pinMode(LedPinA, OUTPUT);
pinMode(LedPinB, OUTPUT);


pinMode(ButtonPinA, INPUT);
pinMode(ButtonPinB, INPUT);
}
void loop()
{
buttonStateA = digitalRead(ButtonPinA);
if (buttonStateA == HIGH && brightnessA != 255)
{
brightnessA ++;
}
if (buttonStateA == LOW && brightnessA != 0)
{
brightnessA --;
}
analogWrite(LedPinB, brightnessA);
Serial.print(brightnessA);

Serial.print("   ");
buttonStateB = digitalRead(ButtonPinB);
if (buttonStateB == HIGH && brightnessB != 0)
{
brightnessB --;
}
if (buttonStateB == LOW && brightnessB != 255)
{
brightnessB++;
}
analogWrite(LedPinA, brightnessB); 
Serial.println(brightnessB);
delay(5);
}
