TCS3200 Color Sensor Arduino and LCD display circuit

In this article we will learn how to Interface Arduino with TCS3200 color sensor and LCD display.
In the last post we will learn how to Interface Arduino with water level indicator using sonar sensor and LEDs in proteus. You can visit our website,
I hope you appreciate my work, let’s discuss about today’s project.

 

 

 

Components:

1. Arduino UNO
2. Battery 9V
3. Resistor variable 10k
4. LCD display
5. Color Sensor
6. Jumper wires

Construction…

• Connect one side of battery with GND pin of Arduino
• Connect 2^nd side of battery with Vin pin of Arduino
• Connect 5v pin of Arduino with +ve pin of variable then connect it with VDD pin of LCD display then connect it with VCC pin of Color senor through one side of resistor
• Connect 2^nd side of resistor with pin A of LCD display
• Connect GND pin of Color sensor with K pin of LCD display
• Connect K, RW, VSS pins of LCD display with GND pin of Arduino through –ve pin of variable
• Connect signal pin of variable with VD pin of LCD display

• Connect S1 pin of Color sensor with pin 10 of Arduino
• Connect S2 pin of Color sensor with pin 11 of Arduino
• Connect S3 pin of Color sensor with pin 12 of Arduino

Working…

The TCS3200 color sensor is a popular sensor for detecting and measuring colors. It works by illuminating an object with white light and then analyzing the reflected light to determine the color of the object. When combined with an Arduino and an LCD display, you can create color detection and display system.

Applications…

1. Color Sorting Machine
2. Color Mixing and Art
3. Paint Mixing
4. Food Quality Testing
5. Educational Tools

Advantages…

1. Precise Color Detection
2. Versatility
3. Integration with Arduino
4. LCD Display
5. Real-time Feedback
