Hi, I made a 6x6x6 LED cube following this instructable : http://www.instructables.com/id/6x6x6-Arduino-LED-Cube/ . When lighted with arduino UNO using a power supply, the LED are really dim and they dont seem to follow the patterns of the code accurately, I followed the instructable completely and was troubleshooting for the past 2 weeks, I made sure each LED was still fit using another external power supply to light them up 1 by 1. I changed the resistors to 100 ohms hoping it would be brighter, but still no difference. I checked each point of my solder to make sure they weren't faulty. I attached pictures of my cube, can anyone tell me what else can I check or fix to make sure it lights up brightly and follows the code patterns? thanks!

Instructables are normally crap. Never use them unless you know more than the author.

Post a schematic, or at least a link to the Instructables. Read the forum rules and post images and links correctly.

I can tell by your pictures that the Instructables is crap because you have no decoupling capacitors at all in the circuit.

6x6x6 LED cube instructables

Here I attached the link to the instructables and the schematic I used, sorry as I am new to Arduino and I heard that instructables had really good detailed posts where I can learn and follow, also I was planning to make a 6x6x6 dimensional cube, which this was one of the very few I could find as most were 3x3x3,4x4x4,8x8x8

That is not a schematic it is a physical layout diagramand as such totally useless for checking the quality of the circuit.

Never listen to idiots. Instructables have a very bad reputation here, it is a very rare one that has no mistakes in them. As I said their is no supply decoupling at all. That tells you the writer hasn't a clue about electronics.
