Magic light cup module KY-027 Magic light cup sensor module pair compatible development board

Product Overview

The mercury switch has an additional independent LED, and two groups can form a magic light cup

Use the mercury switch to detect the tilt state of the module, and use the PWM wave to control the independent LED, so that it can have different degrees of change from light to dark. When the mercury switch detects the tilt, the LED light will become darker and darker, and the other light will become brighter and brighter

Connect the S pin of one module of the magic light cup to the A5 pin on the arduino power board, and the LED control to the digital pin 3 (to realize the PWM function) The other module S is connected to A4, and the LED control is digital pin 4

When the A module pin has a level signal, the LED PWM signal is not the maximum, and the PWM signal increases

When the module B pin has a level signal, the LED PWM signal is not the minimum, and the PWM signal decreases, and then the PWM signal is assigned to LEDA. The contrast value of the PWM signal is assigned to LED B, and the two LEDs increase and decrease.
