So, I'm quite new to programming with the Arduino. I'm working on a pretty simple project and I decided to use the LoL shield as a display. I'm not doing anything too complicated with it I just need to be able to be able to turn the LED's on and off. I've looked all over the internet and even on the LoL shield website I could not find anything to help me out. As far as i can tell it uses an array and each of the slots in the array is a row of the LED's but the values are a complete mystery to me. If anyone who has some knowledge with this shield could help me out, point me to a chart with the values or something it would be greatly appreciated!

but the values are a complete mystery to me.
The values should define which LEDs in the column to light up.
Post a link to the library and the code that is confusing you.
That is the library I'm working with.
I should have been more clear, it's not what the values do that is a mystery to me. It's what to put in for the values. They range from 0-16,000's for values and so far my only way to find out which values will light up specific LED's is just to guess and that would take me weeks to work through it all.
Convert the values to binary. I'm willing to bet that you see a pattern real quick.
I don't exactly work with binary on a regular basis, converting all the values to binary would also be quite time consuming. There are lots of people who have done stuff with this shield and I doubt they went through such a complicated process, it should be much more simple than that.
converting all the values to binary would also be quite time consuming.
I don't see that. Most calculator programs can do it.
Besides, you only need to do it once. 16383 = 11111111111111. So, when you pass 18383 as the value, all 14 LEDs on the row should light up. Change any 1 to 0, and that one LED should not light up.
If you want specific LEDs on the row to light up, put 1s in the value at the appropriate place. All the rest of the digits will be 0. The LOL shield is perfectly happy taking 0b11111111111111 as an input. It does not need the input to be in base 10. In fact, the input will always be binary, because that's all the Arduino knows how to deal with. The compiler manages the conversion from base 10 to binary.
