Generic 2C90009 Magic Light Cup modules KY-027

Product description

Description Magic Light Cup Module is a board which has a led and a mercury tilt switch.

Using PWM to drive the LEDs on the module user can achieve the effect of light being “magically” transferred from one module to the other when tilting them.

In short, it’s 2 components combined, a mercury tilt switch and a led.

On tilting the module mercury inside small tube connect the switching point and make switch ON while tilting it to other side move the mercury and it disconnects the circuit and switch get OFF.

The module operates on 5V DC supply.

So the magic in the name of this module is because when you tilt the switch, the led will turn on and off.

It is also possible to connect it to the NodeMCU.

Overview Operating voltage: 3.3V to 5.5V Compatible with Arduino compatible boards &amp

NodeMCU When you tilt the switch, the led will turn on and off Features Compatible with Arduino &amp

NodeMCU When you tilt the switch, the led will turn on and off Specifications Operating voltage: 3.3V to 5.5V Dimension: 1.5cm x 3.6cm Weight: 10 g Connection Diagram Connect each module using the following diagram.

KY-027 (A) Arduino G GND + +5V S 8 L 9 KY-027 (B) Arduino G GND + +5V S 7 L 6 KY-027 Code In this Arduino sketch we’ll use both modules to create the magic light cup effect.

The mercury switches in each module provide a digital signal that is used to regulate the brightness of the LEDs using using PWM.

Place the modules so the mercury switches on each other are facing in the opposite directions.

Tilting the modules will decrease the brightness on one module while increasing it on the other one, creating the illusion of light magically passing from one module to the other.

// A slow fade out analogWrite(ledPinB, 255 - brightness)

// B slow bright up delay(20)
