About this kit

Mercury switch + LED: tilt to pour light between two cups. The Magic Light Cup Brick is a carrier for the KY-027 module from common 37-in-1 sensor kits: plug the module into the socket and connect one cable to a TinkerPie SENSOR port. A small CH32V003 processor on the brick does the timing work, so your program simply reads the result over I2C.

Features

• Tilt input + PWM LED in one brick
• Use two bricks to pour light
• Brightness 0-255
• Plug the kit module straight into the socket – no jumper wires
• One cable to any TinkerPie SENSOR port (I2C), BUS IN + BUS OUT to chain more bricks
• On-board CH32V003 does the timing – your code just reads the result

Specifications

Safety: The kit has two magic light cups. Use two bricks (one with ADDR +1) to pour light from one cup to the other.

How to use it with TinkerPie

1. Plug the KY-027 module into the 2.54 mm socket on the top edge. Match the pin names: the brick says G + S L, the module has the same letters.
2. Connect BUS IN to any TinkerPie SENSOR 1-4 port with a 4-pin JST-PH cable (the same cable as the other sensors).
3. More bricks? Plug the next one into BUS OUT. Two bricks of the same type need different addresses: bridge ADDR +1, +2 or +4 on the back (0x18-0x1B; the first is 0x18).
4. Install the TinkerPie and TinkerPieBricks Arduino libraries, open the quick-start sketch below, choose the board ESP32S3 Dev Module and upload.

Libraries: TinkerPie and TinkerPieBricks (Arduino IDE: Sketch → Include Library → Add .ZIP Library). Full guide: getting started with TinkerPie Bricks.

Quick start

Upload this, open the Serial Monitor at 115200 baud and watch the TinkerPie matrix.

// Magic Light Cup Brick (TP-K27): quick start
// Reads the brick and shows the value on the TinkerPie matrix and in the Serial Monitor (115200 baud).
#include <TinkerPie.h>
#include <TinkerPieBricks.h>
using namespace tinkerpie;

tpb::KitDual cup;

void setup() {
  Serial.begin(115200);
  tinkerpie::begin();            // also starts the SENSOR ports (I2C bus Wire1)
  if (!cup.begin()) Serial.println("Magic Light Cup Brick not found at 0x18: check the cable to SENSOR 1-4");
  cup.autoFade(true);              // the LED fades by itself when the cup is tilted
}

void loop() {
  Serial.printf("tilted %d\n", cup.input());
  basic::pause(200);
}

Project: Pour the light

Two Magic Light Cup Bricks (the second with ADDR +1 bridged, 0x19). Tilt one cup as if pouring: its light fades out and the other cup fills up.

tpb::KitDual cupA, cupB;
int a = 255, b = 0;

void setup() {
  Serial.begin(115200);
  tinkerpie::begin();            // also starts the SENSOR ports (I2C bus Wire1)
  if (!cupA.begin(0x18)) Serial.println("Magic Light Cup A not found at 0x18: check the cable to SENSOR 1-4");
  if (!cupB.begin(0x19)) Serial.println("Magic Light Cup B not found at 0x19: check the cable to SENSOR 1-4");
}

void loop() {
  if (cupA.input() && a > 0) { a -= 5; b += 5; }   // cup A tilted: pour from A to B
  if (cupB.input() && b > 0) { b -= 5; a += 5; }
  cupA.output(a); cupB.output(b);
  basic::pause(20);
}
