Okay so turns out my local electronics store had some Attiny85 chips. Does the Arduino 1.0 software not support the core attiny45_85 files? I get an error while even compiling the Blink skecth while using Attiny85 w/Arduino as ISP. So it has nothing to do with the wiring or hardware side. I get the error, "OUTPUT not declared in this scope."

Thanks a lot guys. I will be ordering a bunch of Attiny85's and using the Arduino Uno as the programmer.

Judging by the lack of responses, I take it this is not feasible? Would it be easier to just buy the LoL shield? Or if anyone has any LED matrix tutorials for charlieplexing, that would work too.

So if I were to buy the Attiny85, what else would I need to buy to program it with my Arduino? Does the chip include the pinout diagram?

Okay thank you. I take it that the Attiny85 standalone chip wouldn't be prgrammable without additional hardware? Hence the link you sent me? I ask because I can get an attiny85 chip for like $3.00.

Okay so with the Freeduino Arduino-compatible Runtime board Rev B all I would need then would be the Atmega328 chip right? Of course the parts to build my project also. Although it may be a bit big for some of the smaller things I would like to do. What about an Attiny85 or something? Is that programmable with the arduino?

NKC board? I'm not sure what that is. I went to that site dipmicro but I don't see anything NKC board.

Has anyone built one of these? I mean actually built one and not bought the kit. I am starting to venture into charlieplexing after I built the direct drive model. I hate to buy the LoL shield if I can just make it as I already have a mass amount of LEDs. Or if there is a tutorial for making a charlieplexed matrix with Arduino code?

Anything past pin 13 is going to be analog. Pin 14 would be A0. 15 would be A1 and so on. From the looks of the video it is definitely a wiring issue. I built my 8X8 matrix from scratch using my schematic and it works wonderfully. You definitley should use resistors. 8 of them to be exact. Try reversing the wiring. On your matrix where you wired pins 1-8 use 9-16 instead. Good luck.

I am just using a few digital outputs for simple projects such as fading 3 LEDs or blinking. I want to make them permanent.

I know what your problem is. You wired it wrong to the arduino. The diagram is a little tricky on how it is wired. Try this and get back to me. Your rows should be cathodes and the columns should be anodes. I took the liberty and drew this diagram for you.
                                                                                                   

 

Thanks for the reply. So yea I just want the cheapest solution as to where I can upload simple sketches from my Arduino for small LED projects on to something really small. What would work the best and cheapest?

Okay so I have been messing with my Arduino for about a month now and I must say I really love it. I've done the standard LED blinking and cubes and matrixes, and even ventured into charlieplexing. My question is, can I say write a sketch for a simple 3 LED mood lamp and then transfer that sketch or put it on to a small chip of some sort to make it run the same without the Arduino. I had this idea to use lightbulbs as a diffuser. Gutted out ones of course. Because I am building all of these awesome projects with my breadboards and PC boards but I always have to rely on the arduino to do something so simple as a 555 IC chip would do for example. Is there something out there that can make this happen for me? Or am I far fetched? Of course ultimately I am wanting to do the 3 LED mood light in a lightbulb with a nice base to hide the electronics.

Hey thank you for your time and responses. I appreciate the amlicable environment here.
