TINKER PiEDESIGN IN INDIA

Study buddy: phone away!

While you study, TinkerPie watches for a phone in your hand. Pick it up and it beeps and counts; put it away and you get a green tick.

Open in TinkerPie Studio

What you need

Step by step

  1. Open Study buddy: phone away! in TinkerPie Studio. It opens as blocks.
  2. Press Run, then Start camera in the AI camera panel and allow the webcam. No webcam? Use the “Pretend here” controls. The object model (5 MB) downloads the first time, so stay online.
  3. 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.
  4. 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 pickups;

basic.forever(function () {
  if (ai.objectSeen(AiObject.Phone)) {
    basic.showIcon(IconNames.No, Colors.Red);
    music.playTone(1200, 120);
  } else {
    basic.showIcon(IconNames.Yes, Colors.Green);
  }
  basic.pause(300);
});
ai.onObject(AiObject.Phone, function () {
  pickups = (typeof pickups === 'number' ? pickups : 0) + 1;
  serial.writeLine('Phone picked up: ' + String(pickups));
});
input.onButtonPressed(Button.A, function () {
  basic.showNumber(pickups, Colors.Yellow);
});

pickups = 0;
