 Bigger Bigger  Smaller Smaller  Reset Reset

This is the Simon Says game originally by Robert Spann. I realized that Simon says should be easy to do on the arduino. So i Googled around for any previous attempts and found Robert's thread posted nearly a year ago.
http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1235696263

I also saw several videos on Youtube, but couldn't find the code for them. Some had sound with them but Robert's didn't. So i took the code, before he added sound to his, and trimmed it down a bit. I  then added my own version of sound coding to it using the Tone.h library. One thing i liked about the code was the cheat functionality too it. It reports to the PC what lights where light making it easy to just follow the numbers on the serial monitor. This is great for troubleshooting the code so i left it in. The hardware setup of the push buttons is different form his. I changed the code to allow the buttons to be set up without a pull down resistor.

Here is my updated version of Robert Spann's Simon Says game.
Thank for the code Robert (a.k.a jackal858).

Code:
/*Simon Says game. Now with sound effects.

Originaly made by Robert Spann
Code trimmed and sound effects added by digimike

Buttons are to be set on there designated pins without pull
down resistors and tied to ground. Internal pull down resistors
will be in use. Logis is reversed.

Code:
digitalWrite(button[x], HIGH);  // buttons start in high possition
A better comment would be "// enable pull-ups"

There's a 50:50 chance I disagree.   ;D  

It depends on the audience and the intent.  If the audience is his future self and the intent is to remind him that the logic is reversed, then it's a good comment.  (well, the comment would work for me)  If the audience is the world-at-large and the intent is to describe the purpose of the function call, then your comment is certainly better.  The best comment would be...

Code:
digitalWrite(button[x], HIGH);  // enable internal pullup; buttons start in high position; logic reversed

But who has time for all that typing!   :smiley


@digimike: Thanks for posting about your project.  I love reading what other people do with Arduinos!

@Groove: Thanks for posting about comments.  It's good (at least for me) to discuss these things so we can get better at our craft.

Made a couple of amendments to the code. The OP has been updated with these changes since they are minor ones. First i was bothered that the original code had the void loop() at the end of the code with nothing in it just so it would compile. So i changed the void output() to void loop() to get rid of the extra line of code. I then added a tune to the start of the game. Upon competition of each turn this tune is played again.

Hi I used digimike's code to make a Simon/Arduino Says game for a Halloween party next weekend.  I am going to try to attach the youtube video below. http://crazyideafactory.com/?p=1013
