About this kit

Detects tilt with a mercury capsule. The Mercury Tilt Switch Brick is a carrier for the KY-017 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

• Tilted / level
• Tilt event counter
• Handle with care – glass capsule
• 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: This module contains a little mercury in a sealed glass capsule. Do not break it; check your school rules before buying.

How to use it with TinkerPie

1. Plug the KY-017 module into the 2.54 mm socket on the top edge. Match the pin names: the brick says S + -, 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 (0x08-0x0F; the first is 0x08).
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.

// Mercury Tilt Switch Brick (TP-K13): 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::KitSensor s;

void setup() {
  Serial.begin(115200);
  tinkerpie::begin();            // also starts the SENSOR ports (I2C bus Wire1)
  if (!s.begin()) Serial.println("Mercury Tilt Switch Brick not found at 0x08: check the cable to SENSOR 1-4");
}

void loop() {
  bool level = s.state();            // the S pin, debounced
  uint8_t n = s.events();            // how many times it fired (counts up, wraps at 255)
  Serial.printf("S = %d   events = %u\n", level, n);
  if (level) led::fill(Colors::Green); else basic::clearScreen();
  basic::pause(100);
}

Project: Tilt alarm box

Put the brick in a box. If someone tilts or opens it, TinkerPie beeps. This module contains mercury in a sealed glass capsule: do not break it.
