REES52 Magic Light Cup Module For Arduino Starters Compatible Light Electronic Hobby Kit

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()
