Hi! I'm relatively new at coding so I'm not sure what I did wrong. I tried copying the book. I got a message after compiling it that was essentially this:
Arduino: 1.7.11 (Windows 8.1), Board: "Arduino Uno"
arduinofirst.ino: In function 'void loop()':
arduinofirst.ino:38:16: error: 'BlueSensorValue' was not declared in this scope
arduinofirst.ino:50:13: error: 'redREDPin' was not declared in this scope
*Error compiling. *
The code I wrote:
const int greenLEDPin = 9;
const int redLEDPin = 11;
const int blueLEDPin = 10;
const int redSensorPin= A0;
const int greenSensorPin = A1;
const int blueSensorPin = A2;
int redValue = 0;
int greenValue = 0;
int blueValue = 0;
int redSensorValue = 0;
int greenSensorValue = 0;
int blueSensorValue = 0;
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
pinMode(greenLEDPin,OUTPUT);
pinMode(redLEDPin,OUTPUT);
pinMode(blueLEDPin,OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
redSensorValue = analogRead(redSensorPin);
delay(5);
greenSensorValue = analogRead(greenSensorPin);
delay(5);
blueSensorValue = analogRead(blueSensorPin);
Serial.print("Raw Sensor Value \t Red: ");
Serial.print(redSensorValue);
Serial.print("\t Green: ");
Serial.print(greenSensorValue);
Serial.print("\t Blue: ");
Serial.println(BlueSensorValue);
redValue = redSensorValue/4;
greenValue = greenSensorValue/4;
blueValue = blueSensorValue/4;
Serial.print("Mapped Sensor Values \t Red: ");
Serial.print(redValue);
Serial.print("\t Green: ");
Serial.print(greenValue);
Serial.print("\t Blue: ");
Serial.println(blueValue);
analogWrite(redREDPin, redValue);
analogWrite(greenLEDPin,greenValue);
analogWrite(blueLEDPin, blueValue);
}
I would really appreciate an input.
