Arduino Uno

[The Boloblur]

You would have better luck trying to do that with a Raspberry Pi rather than the Arduino Uno However they can both run full versions of Windows, Linux, and Mac OSX

On second thought, Nixie tubes take a lot of juice...

[The Boloblur]

I am sure that if you look into it, someone has done something that you are looking at doing

Yeah, I didn't sit through the whole vid myself, seeing it was over 6 hrs. long, I just went by what the title relayed.

This is my first somewhat complex program to make an LED turn on and off, and make it fade in and out when the button is pressed. I know it is extremely simple, but as I said before I would keep posting about what I am learning.

Code: Select all

// Example 05: Turn on LED when the button is pressed
// and keep it on after it is released
// including simple de-bouncing.
// If the button is held. brightness changes

const int LED = 9;    // the pin for the LED
const int BUTTON = 7; // the input pin of the pushbutton

int val = 0;    // stores the state of the input pin

int old_val = 0; // stores the previous value of "val"
int state = 0;   // 0 = LED off while 1 = LED on

int brightness = 120;   // Stores the brightness value
unsigned long startTime = 0; // when did we begin pressing?

void setup() {
  pinMode(LED, OUTPUT); // tell Arduino LED is an output
  pinMode(BUTTON, INPUT); // and BUTTON is an input

}

void loop() {

  val = digitalRead(BUTTON);  // read input value and store it

//check if there was a transition
if ((val == HIGH) && (old_val == LOW)) {

  state = 1 - state;  //change the state from off to on
                      // or vice-versa
  
  startTime = millis(); // millis() is the Arduino clock
                        // it returns how many milliseconds
                        // have passed since the board has
                        // been reset.


  // (this line remembers when the button
  // was last pressed)
  delay(10);                      
  }
  // check whether the button is being held down
  if ((val == HIGH) && (old_val == HIGH)) {

    // If the button is held for more than 500ms
   if (state == 1 && (millis() - startTime) > 500) {
    brightness++; //increment brightness by 1
    delay(10);    // delay to avoid brightness going
                  // up too fast

   if (brightness > 255) { // 255 is the max brightness

                   brightness = 0; //If we go over 255
                                   // let's go back to 0
      }
    }
  }

old_val = val;   // val is now old, let's store it

if (state == 1) {
  analogWrite(LED, brightness); // turn LED ON at the
                                // current brightness level
} else {
  analogWrite(LED, 0);  // turn LED OFF
                              }
  
}

i looked at this tech once for building an arcade cabinet. using one of these to wire all the buttons if i remember right.

[The Boloblur]

very possible. I will have to ask my dad, but I think he has the start to a arcade machine and I might be able to get the code for you if you wanted to look over it.

[perrinoia]

OMG, I want to build this!

[KILROY]

WOW, that looks pretty awesome Perr! Question though, I notice it has controllers on both sides. Does the screen flip allowing the other person to view it as they should? I'm assuming it does.

[perrinoia]

Good question... I think player 2 just has to play upside down.

I saw another arcade in a barrel where both sets of controls were on one side..

I originally thought that one would be better because the players wouldn't be bumping shoulders while playing, but now that you mention it, playing upside down might be worse.
