Digital Dice: an Arduino project.

People like games "high tech". For example: in my country there is a game called "Monopoly". In that game one must collect "streets" by buying them with money.
That game recently released a version where one doesn't pay with paper but with a credit card.

I was starting to think about what else i couldd modernise...
OMG... I thought while throwing the dice.
10 minutes and a game I won later I started learning Wiring.
when I could do that I bought an Arduino.



Why this Instructable is in the efficiency contest:
The battery's used in the Arduino are rechargables, these can be charged over 1000 times! No throwing away battery's!!

Step 1 Materials and tools.

• Arduino
• Power for Arduino.
• 7 LED's.
• Suitable box.
• Wire.
• Switch

Tools:

• Soldering Iron.
• Hot glue.
• Dremel.
• Some items like a ruler, I won't actually tell when to use them but it should come in handy.

So how exactly does the dice work? do you press the button then it shows a different number?? Keen to make similar project

[dunnos]

press button-> value is displayed for five seconds -> need to press button again for new value

[anand-patel]

Thanks, also how do you connect the wires to arduino??

[dunnos]

Well, there are three options, you either:
1) solder to the board directly
2) make a cheapy header with paperclips (what I did in this instructable)
3) buy headers to solder to (what I do now with all my projects)

Your choice!

[anand-patel]

Awesome, I tried this and it worked perfectly! One change I would like to make is to have the lights flash randomly before settling on a number (simulating the 'rolling' of a die) - could you help me out?

[dholroyd]

I could download this code??

what part of the code sets how long the lights stay on for before switching off

very good Instructable!

I got a question tough

do the numbers on the digital dice just change very fast (ex:every millisecond)?

also,the circuit thing is nice but it would be MUCH easier if you had a prototyping shield on so you could just snap the LED's in there and run some jumper wires to the digital pins

also,if anybody knows a project (similar to this) in which you press a button and the LED's display a number and keeps it on unless you press the button one more time,which will display another number...please respond

[dunnos]

thanks! glad to hear you like it! for your question: i think you mean how the numbers are generated? well, the arduino cycles through all 6 numbers every (insert time here). this goes so fast you cant be able to manipulate it being 6 all the time. I am currently looking for a protoshield :P ik would've used one if i had it but i still wouldve put it in this box afterward. i uploaded a second code called DigitalDice_with_press. i didn't test it so you will have to do that for me. so please tell me the results! Greetings from holland, Dennis

another thing...I an new to the arduino which I got a week ago and the second code (DigitalDice_with_press),its the same soldering and things except that you connect a push button (or switch) to it instead of the ON/OFF switch,right? i am waiting for a response...this is a really cool project and I intend to make it I will test it out after I can get the answer to my questions thanks

[dunnos]

arduino rules huh?
uhm... i don't know how you got the idea of an on off swith but in both the programs there is a pushbutton =/

in any case, the first program resets after 5 seconds or so and the second program resets when you push the switch for the 2nd time
so the 2nd is like: push-look at number-push again to reset-repeat.

if there is a problem with the 2nd sketch i need to know exactly what it is ok?

[coolrobot]

here's the thing...i have tried like 4 arduino projects and for some reason (me) none of them worked even if i connected everything well and double chacked. i also tried this one and it doesnt work for me...if it works for anyone...then maybe its my stupid protoshield kit that was missing 3 female headers that should be pluged in the icsp pins and then on the protoshield maybe it doesnt work,maybe its me but i will check out the first one to see if it works for me... sorry...

yes, monopoly is the most succesful board game in my country, in fact, it is the only board game i actually like. kidding about what? where did the last bit come from? reding reading...

o-kay? may i ask where i even sayd reading then?

[dunnos]

so you just thought "that is a nice 'ible, let's spam about reading!

[TXTCLA55]

Hmmm; some diagrams of how to wire all the LED's to the arduino would be nice....but over all a great ible! 5 starts!

[dunnos]

Will do, first thing in the morning! thanks!
