Hi
I have spent the last three nights trying to debug this sketch and getting no where. Every time i run the program i am prompted for a color. I am getting a reply back saying that is not a valid color.
Sorry in advance if i am in the wrong section and can any one direct me where to get help.
Serial.begin(9600); //Turn on Serial port
pinMode(redPin, OUTPUT); //Set redPin to be an output
pinMode(greenPin, OUTPUT); //Set greenPin to be an output
pinMode(bluePin, OUTPUT); //set bluePin to be an output
}
void loop() {
Serial.println("What color would you like the LED? (red, green, or blue)"); //Prompt user for color
while (Serial.available()==0) { } //Wait for input
colorChoice = Serial.readString();
if (colorChoice=="red") {
analogWrite(redPin, brightness); //turn on red pin
analogWrite(greenPin, 0); //turn off green pin
analogWrite(bluePin, 0); //write off blue pin
}
if (colorChoice=="blue") {
analogWrite(redPin, 0); //turn off red pin
analogWrite(greenPin, 0); //turn off green pin
analogWrite(bluePin, brightness); //write on blue pin
}
if (colorChoice=="green") {
analogWrite(redPin, 0); //turn off red pin
analogWrite(greenPin, brightness); //turn on green pin
analogWrite(bluePin, 0); //write off blue pin
}
if (colorChoice!="red" && colorChoice!="green" && colorChoice!= "blue") {
Serial.println("That is not a valid color choice, please try again");
Serial.println("");
}
}
