Hi,
I'm brand new to Arduino and already having an issue with the 3rd tutorial that came with my elegoo kit. I just cant change the colors and it doesnt do anuthing whrn I changr the values. I can only get the fading time to change.
Here is the code:
`// Define Pins
#define BLUE 3
#define GREEN 5
#define RED 6
void setup()
{
pinMode(RED, OUTPUT);
pinMode(GREEN, OUTPUT);
pinMode(BLUE, OUTPUT);
digitalWrite(RED, HIGH);
digitalWrite(GREEN, HIGH);
digitalWrite(BLUE, HIGH);
}
// define variables
int redValue;
int greenValue;
int blueValue;
// main loop
void loop()
{
#define delayTime 5// fading time between colors
redValue = 255;// choose a value between 1 and 255 to change the color.
greenValue = 0;
blueValue = 0;
// this is unnecessary as we’ve either turned on RED in SETUP
// or in the previous loop … regardless, this turns RED off
// analogWrite(RED, 0);
// delay(1000);
for(int i = 0; i < 255; i += 1) // fades out red bring green full when i=255
{
redValue -= 1;
greenValue += 1;
// The following was reversed, counting in the wrong directions
// analogWrite(RED, 255 - redValue);
// analogWrite(GREEN, 255 - greenValue);
analogWrite(RED, redValue);
analogWrite(GREEN, greenValue);
delay(delayTime);
}
redValue = 0;
greenValue = 255;
blueValue = 0;
for(int i = 0; i < 255; i += 1) // fades out green bring blue full when i=255
{
greenValue -= 1;
blueValue += 1;
// The following was reversed, counting in the wrong directions
// analogWrite(GREEN, 255 - greenValue);
// analogWrite(BLUE, 255 - blueValue);
analogWrite(GREEN, greenValue);
analogWrite(BLUE, blueValue);
delay(delayTime);
}
redValue = 0;
greenValue = 0;
blueValue = 255;
for(int i = 0; i < 255; i += 1) // fades out blue bring red full when i=255
{
// The following code has been rearranged to match the other two similar sections
blueValue -= 1;
redValue += 1;
// The following was reversed, counting in the wrong directions
// analogWrite(BLUE, 255 - blueValue);
// analogWrite(RED, 255 - redValue);
analogWrite(BLUE, blueValue);
analogWrite(RED, redValue);
delay(delayTime);
}
}`
The values that I changed are the first ones right where it says in parenthesis to choose the value. No matter what i do it keeps fading between red, blue, and green everytim I load it. Then sometimes, without changing anything and doing it all over, it just fades in and out of hlue. Im very confused if, first of all, im changing the calues in the correct section, and what I could possibly be doing wrong as I have checked the wiring over and over.
Thank you for any help.
