Led Block with 64 led's. I think it is bi-color red/green. 12 pins on one side of bottom and 12 on other side. Does anyone know how to wire these up ??? Thanks Nathan

I recieved these blocks from a person giving away some of his unused electrical stuff. He gave me a box with some neat stuff and some really bad stuff. But no data sheet was included. I think I researched and found it should be a bi-color led but I have found no other data. Especialy wiring.
Thanks
I havn't found a data sheet yet, I found this I don't know if it can help you. I did not understand all of it. I will continue to look for data sheet but does not look promising.
Thanks
There are multiple ways.... (as usual)
There are these chips from Maxim called MAX7219 that can drive up to 8x8 leds matrices. They are very simple to wire up, you just need a resistor and a capacitor. in the arduino distribution there should be some code called MAX7219 (written by Nick Zambetti) that shows how to send data to these guys.
you can find a schematic here in the datasheet https://www.electro-tech-online.com/custompdfs/2008/12/MAX7219-MAX7221-1.pdf
this can drive even fairly bright LEDs.
I'll attach the code here.
