Button and Diodes

Here is my gif for assignment 1! It shows the GIOP diode fading in red, blue, and green, and the red, blue, and green LEDs turning on (right).

I was having some trouble getting the button to work, so I had to connect it with wires. It's also kind of of hard to tell what is happening in the the video, but when the LEDs turn on, they stay on while the rest are turning on. Then at the end of the cycle, all the LEDs turn off.

Here is my schematic (below)! The schematic shows how my circuit board should be connected.

This is the code I used to make my the LEDs and GIOP on my arduino blink and fade!

// constants won't change
const int buttonPin = 13; // number of the button pin
const int redPin = 3; // number of the red GPIO pin
const int bluePin = 6; // number of the blue GPIO pin
const int greenPin = 5; // number of the green GPI pin
const int rPin = 11; // number of the red LED pin
const int gPin = 10; // number of the green LED pin
const int bPin = 9; // number of the blue LED pin

// variables will change
int buttonState = 0; // reading button status

// setup runs once
void setup() {
pinMode(redPin, OUTPUT); // initialize red GPIO pin as output
pinMode(bluePin, OUTPUT); // initialize blue GPIO pin as output
pinMode(greenPin, OUTPUT); // initialize green GPIO pin as output
pinMode(rPin, OUTPUT); // initialize red LED pin as output
pinMode(bPin, OUTPUT); // initialize blue LED pin as output
pinMode(gPin, OUTPUT); // initialize green LED pin as output
pinMode(buttonPin, INPUT); // initialize button pin as output
}

// loop function repeats forever
void loop() {
buttonState = digitalRead(buttonPin); // read button status value

if (buttonState == HIGH) { // check if button is pressed (buttonState HIGH)

for (int i = 0 ; i < 200; i = i + 8) { // fade from 0 to 200 by increments of 8
analogWrite(redPin, i); // fade using red GPIO pin
delay(20); // between each increment wait 20 milliseconds
}

digitalWrite(rPin, HIGH); // turn on red LED

for (int i = 200 ; i >= 0; i = i - 8) { // fade from 200 to 0 by increments of 8
analogWrite(redPin, i); // fade using red GPIO pin
delay(20); // between each increment wait 20 milliseconds
}

delay(300); // wait 300 milliseconds

for (int i = 0 ; i < 25; i ++) { // fade from 0 to 25 by increments of 1
analogWrite(greenPin, i); // fade using green GPIO pin
delay(20); // between each increment wait 20 milliseconds
}

digitalWrite(gPin, HIGH); // turn on green LED

for (int i = 25 ; i >= 0; i --) { // fade from 25 to 0 by increments of 1
analogWrite(greenPin, i); // fade using green GPIO pin
delay(20); // between each increment wait 20 milliseconds
}

delay(300); // wait 300 milliseconds

for (int i = 0 ; i < 25; i ++) { // fade from 0 to 25 by increments of 1
analogWrite(bluePin, i); // fade using blue GPIO pin
delay(20); // between each increment wait 20 milliseconds
}

digitalWrite(bPin, HIGH); // turn on blue LED

for (int i = 25 ; i >= 0; i --) { // fade from 25 to 0 by increments of 1
analogWrite(bluePin, i); // fade using blue GPIO pin
delay(20); // between each increment wait 20 milliseconds
}

delay(300); // wait 300 milliseconds

digitalWrite(rPin, LOW); // turn off red LED
digitalWrite(gPin, LOW); // turn off green LED
digitalWrite(bPin, LOW); // turn off blue LED

} else {
// nothing happens
}
}

Here is my math for how I chose the proper resistance to use (below). I chose to use 330 ohms of resistance for all the LED lights, 220 ohms of resistence for the GIOP light, and 220 ohms of resistence for the button. These are all higher than the minimum resistance required found in my calculations.
