Colour detective
Hold something over a TCS34725 colour sensor: the whole matrix lights up in its colour.
What you need
- TinkerPie V1 board (or the free online simulator)
- USB-C data cable
- Colour sensor TCS34725
Wiring
TCS34725 → SENSOR port. Its white LED lights the object.
Step by step
- Open Colour detective in TinkerPie Studio. It opens as blocks.
- Wire it: TCS34725 → SENSOR port. Its white LED lights the object.
- Press Run to try it in the simulator. Use the sliders and buttons under the board picture to test it.
- 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.
- 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.

led.fill(sensors.colourSensorColour());
