KY-027 Magic Light Cup Sensor Module

• Two boards make up the KY-027 Magic Light Cup module.
• Each one has a mercury tilt switch and an LED.
• The name comes from the effect of light being "magically" transferred from one module to the other when tilted, like to pouring water from one cup to another, thanks to PWM driving the LEDs on each module.
• Compatible with common electronics platforms like as ESP32, Arduino, and Raspberry Pi.
