Cloud thermometer (ThingSpeak)

What you need

• TinkerPie V1 board (or the free online simulator)
• USB-C data cable
• A 2.4 GHz Wi-Fi network and a phone

Wiring

Put your Wi-Fi name and password in the first block. Then open the address shown in the console on a phone on the same Wi-Fi. Make a free channel at thingspeak.com with 2 fields and paste its Write API Key into the program.

Step by step

1. Open Cloud thermometer (ThingSpeak) in TinkerPie Studio. It opens as blocks.
2. Wire it: Put your Wi-Fi name and password in the first block. Then open the address shown in the console on a phone on the same Wi-Fi. Make a free channel at thingspeak.com with 2 fields and paste its Write API Key into the program.
3. Press Run to try it in the simulator. Use the sliders and buttons under the board picture to test it.
4. Type your Wi-Fi name and password into the connect to Wi-Fi block.
5. 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.
6. 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.

basic.forever(function () {
  iot.thingspeakSend('YOUR_WRITE_KEY', input.temperature(), input.lightLevel());
  basic.showLeds('......|......|..X...|......|......', Colors.Green);
  basic.pause(500);
  basic.clearScreen();
  basic.pause(19500);
});

wifi.connect('my-wifi', 'my-password');

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