No, you can't directly use a UNO. As explained in step 1, the UNO works with TTL (5v) digital levels, and the bluetooth module works with 3.3v. So with 5V, you can damage the bluetooth module. The solution in this case is to use a level converter, to adapt the digitals levels between the UNO and the bluetooth module.
Quite beautiful !!!

Thanks for sharing !!! Always a pleasure to get feedback !!
The difficulty should be to add the connector protection... You know, the plastic part that translate to unprotect the connectors.But it can work without of course !!

This is so... incredible ! I have to try this !!
Never used it but yes, it should work the same...
So the translation works, but very slow ? How many time there is between two "translations" ? The code seems fine, for now I don't see what can be the problem...What Arduino board are you using ?
For the scrolling problem, can you describe what do you see ? No scrolling ? Wrong direction ?
Could you share YOUR code please ? I can take a look.Maybe the "k" variable is missing somewhere to translate the text...?
It should work the same, we just swap lines and columns for the display.

It seems that a library is missing...Check this page :http://playground.arduino.cc/Main/LedControldownload links at the bottom.
You are welcome !!
Ahhh... Hmmm... In this case you should try lc.setColumn(MatrixNumber-m,i,Buffer_inverse[i+k+8*m]); to reverse the order. Maybe add 1 or -1 to make sure you use all the modules.Let me know...
Check the end of the code : you have one "if" statement to remove.This one : if (m % 2 == 0) //check is the module is upside-down or not...
Ok I see... In this case you will have to modify an other statement at the end of the code. You can try to change the lc.setRow(m,i,Buffer_inverse[i+k+8*m]);by lc.setColumn(m,i,Buffer_inverse[i+k+8*m]);(not tested !!)As your modules are in a different way. You will not write the data on rows, but on the colums instead.

Because each letter is 6 columns "wide" ! (5 in fact, but a blank column is added between two characters).
Captive Ring Puzzle
Sorry for my delayed answer.You have different ways to add an other player :-you can use a second ultrasound module wired on the arduino. Of course, you will have to send the two information to the game, and add an other plane-or you can play with the mouse or keyboard, instead of adding an other ultrasound device.Let me know if you need more details !

Yes of course, you just have to remove one "IF" statement at the end of the program.Check the other comments, someone already ask me the same thing. Just ask again if you need help. I don't have time now, but I can send you the updated program....!

Please try with one led module and without the bluetooth one. (use the program given in the last step).Your card is an arduino nano ?
