Water tank level

A water level sensor fills a blue bar graph and beeps FULL at the top.

What you need

Wiring

Water level sensor: S → P10, + → 3.3 V, − → GND.

Step by step

  1. Open Water tank level in TinkerPie Studio. It opens as blocks.
  2. Wire it: Water level sensor: S → P10, + → 3.3 V, − → GND.
  3. Press Run to try it in the simulator. Use the sliders and buttons under the board picture to test it.
  4. Connect TinkerPie with a USB-C cable in Chrome or Edge, press Connect, then Download. Or, with Studio started from the TinkerPie launcher on your computer, open the Arduino C++ tab and press Build & Flash.
  5. Change something: a colour, a number, a sound. Then run it again.

The code

This is the program the blocks make. The same program runs in the simulator and on the board.

JavaScript
var level;

basic.forever(function () {
  level = sensors.waterLevel(Pin.P10);
  led.plotBarGraph(level, 100);
  serial.writeValue('level', level);
  if (level > 90) {
    basic.showString('FULL', Colors.Blue);
    music.beep();
  }
  basic.pause(400);
});
Arduino C++ (TinkerPie library)
// Water tank level
// Arduino C++ made by TinkerPie Studio from the blocks. Board: TinkerPie V1 (ESP32-S3).
// Arduino IDE: install the TinkerPie library (Studio menu > Arduino library), then Tools > Board > ESP32S3 Dev Module,
// USB CDC On Boot: Enabled, Flash Size: 16MB, Partition Scheme: 16M Flash (3MB APP/9.9MB FATFS), PSRAM: OPI PSRAM.
#include <TinkerPie.h>
using namespace tinkerpie;

double level = 0;

void setup() {
  tinkerpie::begin();
  basic::forever([]() {
    level = sensors::waterLevel(Pin::P10);
    led::plotBarGraph(level, 100);
    serial::writeValue("level", level);
    if (level > 90) {
      basic::showString("FULL", Colors::Blue);
      music::beep();
    }
    basic::pause(400);
  });
}

void loop() {
  tinkerpie::loop();   // runs the forever blocks and handles events
}
