ARDUINO COLOR DETECTION USING TCS34725 AND OLED DISPLAY

INTRODUCTION

Color deection is important concept of electronic and automation and automation sytem in this project we the TSC34725 RGB color sensor along aurduino and OlED display to detect and display the different color in realtime..

The TSC34725 RGB color sensor is highly accurate that measure Blue ,Red and Green value.using these value the system idetifies the color of object place in front of sensor.

REQUIRED COMPONANTS

1. TSC34725 color sensor

INSTALL REQUIRED LIBRARY

WORKING:-

1. Aurduino Uno act as main controller
2. TCS34725 RGB Sensor Detect RGB value and Send data to Aurduino Uno.
3. And Aurduino Uno process the data and send to OLED Display
4. Both OLED And TCS34725 RGB sensor are connected using I2C communication (SDA and SCL line)
5. The OLED Display shows the RGB value and shows the Detected color

APPLICATION

1. Color sorting machine
2. Used in Industries to Automaticaly sort the object based on color.
3. Smart Dustbin system
4. Help in wast Segregation by idetifing different type of material
5. Industrial Automation
6. Used in production line for quility control and color based inspection.

4 object detection system

1. idetifies object based on their color in robotics and Automtion

CONCLUSION

In this project we succusefully built color detection system using TCS34725 RGB sensor,Aurduino Uno and OLED Display.The system is cabale of detecting diffrent color and display Realtime RGB value.Along with Idenfied Color Name
