How to Use the GY-33 TCS34725 Color Sensor

Choose Communication Mode:
- I2C Mode: Connect PinA (S0) to GND. The module enters I2C mode.
- Direct Sensor Mode: Connect PinB (S1) to GND. The module directly controls the TCS34725 chip.
Connect to a Microcontroller:
- For I2C communication: Use SDA & SCL pins.
- For Serial communication: Use TX & RX pins.
Power the Module:
- Supply 3V - 5V to the VCC pin.
- Connect GND to the ground of the microcontroller.
Read Color Data:
- Using I2C, read the RGB values from the sensor registers.
- Using Serial, the sensor automatically outputs color values.
Adjust LED Brightness (Optional):
- The brightness of the onboard LED can be controlled via I2C or Serial commands.
