Random Arduino Fun

Here's what I came up with putzing with different code projects. As you hold the button down, the light will flicker and pulse, but when it's not pressed, you have manual control turning it up or down. Here's the code:


int ledPin = 6;

int buttonPin = 3;

int buttonPressed = 0;

int bright = 0;

int dir = 1;

int potPin = A0;

int newValue = 0;

int potValue = 0;

void setup(){
  Serial.begin (9600);

  pinMode (ledPin, OUTPUT);

  pinMode (buttonPin, INPUT);

  pinMode (potPin, INPUT);

  digitalWrite (buttonPin, HIGH);
}

void loop (){

  buttonPressed = digitalRead (buttonPin);

    Serial.println (buttonPressed);
 
    bright = bright + dir;
    delay (100);
 
     potValue = analogRead(potPin);

  newValue = map(potValue, 0, 1023, 0, 200);

//Serial.print (potValue);

Serial.println (newValue);
 
    if (buttonPressed == 0){
      digitalWrite(ledPin, HIGH);
  dir += -1;
    }
 
    else{
      analogWrite (ledPin, newValue);
      bright = newValue;
    }

  analogWrite(ledPin, bright);

  if (bright >= 255){
    bright = 0;
  }
}

By The Press of a Button

By now, you've no doubt been blown away. When not pressing the button, the red light shines. When you do press the button, the blue light pulses. Here's the code:

Three Lights

Check these lights out! Blink, blink, blink, BLINK! Here's the code:

Basic Code

Oh man, check this out! It prints stuff, it loops, and it milks a meme from 2007! Cooooooooool!!!

Project #1

I made this. It was fun. It dims. The video's audio is general jackass-ery. No apologies.
