Sensor Description The KY-027 Magic Light Cup module consists of two boards, each equipped with an LED and a mercury tilt switch. By utilizing PWM to control the LEDs on both modules, you can simulate the visual effect of light “magically” transferring between them when they are tilted, reminiscent of pouring water between cups, which inspired […]
