I'm new to arduino. I had found an interesting project to work on with, but unfortunately I'm held up at compilation error. I tried finding answers to this problem but not able to understand.
Here is my code:
// Include Libraries
#include <Wire.h>
#include <Servo.h>
#include <Adafruit_TCS34725.h>
// Initialize Sensors
Adafruit_TCS34725 tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_50MS, TCS34725_GAIN_4X);
Servo myservoRed;
Servo myservoGreen;
Servo myservoBlue;
int posRed = 0;
int posGreen = 0;
int posBlue = 0;
void setup() {
Serial.begin(9600);
Serial.println("Color View Test!");
if (tcs.begin()) {
Serial.println("Found sensor");
} else {
Serial.println("No TCS34725 found ... check your connections");
while (1); // halt!
}
//Attach servos to ouput pins
myservoRed.attach(9);
myservoGreen.attach(6);
myservoBlue.attach(3);
// Initialize Fan pin
pinMode(7, OUTPUT);
}
void loop() {
uint16_t clear, red, green, blue;
tcs.setInterrupt(false);
delay(60); // takes 50ms to read
tcs.getRawData(&red, &green, &blue, &clear);
tcs.setInterrupt(true);
Serial.print("C:\t"); Serial.print(clear);
Serial.print("\tR:\t"); Serial.print(red);
Serial.print("\tG:\t"); Serial.print(green);
Serial.print("\tB:\t"); Serial.print(blue);
// Map color to motor position
posRed = map(red,100,10000,10,80);
Serial.print("\tRedPos:\t"); Serial.print(posRed);
posGreen = map(green,100,10000,10,80);
Serial.print("\tGreenPos:\t"); Serial.print(posGreen);
posBlue = map(blue,100,10000,10,80);
Serial.print("\tBluePos:\t"); Serial.print(posBlue);
Serial.println();
// Write position to motor
myservoRed.write(posRed);
delay(100);
myservoGreen.write(posGreen);
delay(100);
myservoBlue.write(posBlue);
delay(100);
}
