Summary

The TCS3200 is a static RGB color sensor with four filters (red, green, blue, clear). The output is a square wave whose frequency is proportional to light intensity. The module includes four white LEDs for illumination.

Commands and examples – verify before use:

sudo apt-get install p7zip-full
sudo wget https://files.waveshare.com/upload/3/33/Color-Sensor-code.7z
7z x Color-Sensor-code.7z -o./Color-Sensor-code
cd ~/Color-Sensor-code/Pico/c/build/
cmake ..
make -j9
cp main.uf2 /media/pi/RPI-RP2/

Notes and version constraints

The Pico examples assume the provided MicroPython firmware; with different firmware the code may run abnormally.
STM32 examples are based on STM32F103RB; other boards require custom wiring and code adaptation.
White balance adjustment must be repeated after every reset or change of the light source.
External ambient light distorts measurements; for reliable results, test the module inside a closed, non-reflective box.
