Line Following Car with Color Recognition and EasyVR 3 Speech
This project uses a line tracking car to follow a 15mm line on the ground and as it passes a detected color (Red, Blue or Green) it will say the color out loud using the EasyVR 3 speech module. The tracking robot car runs independently from the Arduino Uno. The Arduino Uno processes the detected color from the GY-31 TCS3200 Color Sensor Recognition Module and then speaks the name of the color using the EasyVR 3 speech module.
Some side notes:
The car must be calibrated to follow the line. This can be done by adjusting the two rear potentiometers and the bolt in the front of the car.
The threshold of each color detected should be calculated based on the distance of the TCS3200 Color Recognition Module from the floor.
