Circuit Documentation

Summary

This circuit integrates an Arduino UNO microcontroller with an Adafruit TCS34725 RGB Color Sensor and an HC-SR04 Ultrasonic Sensor. The Arduino UNO serves as the central processing unit, interfacing with the TCS34725 for color sensing and the HC-SR04 for distance measurement. The TCS34725 communicates with the Arduino over the I2C protocol, while the HC-SR04 uses digital I/O pins for triggering and echo signal processing.
