Hi there i like to build a cube but i like to use White led 2.1v-2.4v 20ma. Do i need to use other resistors. Best regards

Hi you can use 220 ohm resistors so you will have a current around 13mA, I think it is enough. If you want you can use also 330 ohm resistors so you will have a current around 8mA. You can choose one of it considering the best quantity of light for you.

Ok, you can calculate the necessary resistance in this way: (average voltage)/current In this case for a current around 10mA you need: (5V-3.25)V/10mA=175 ohm, You should use a resistor around this value. Obviously 5V is the supply voltage.

I have a problem: I made a 6 x 6 x 6 LED Cube, and I found that the brightness of each layer is different from that of each column. Each layer is bright, and each column is dark. The reason is that each layer of each LED is powered directly by each IC pin. Each row of LEDs is in parallel. Six LEDs share the current of IC pins in parallel. The current of each LED is only one sixth of the current provided by IC pins, so the brightness is darker. I want to ask you how to deal with this problem. Thank you very much.

Hi, you can solve this problem with the technique of multiplexer, you can divide the image in some frames each frame is easier than the entire image and the combination of all frames create the image. In this way you can use less LEDs at the same time and the IC can provide the necessary current.

I like your project very much. I haven't studied Arduino for a short time. I plan to make this. I don't understand some parts of your code very well. I want to see a complete code. Can you send me a complete code? My mailbox jy00796180@gmail.com I has one more question： I don't understand, 74HC574 CLK is high level output or low level output? Thank you very munch

Hi I like your led cube i think you did great job i been trying to make one for long time haven't been able to do don't have a lot of knowlege and I would like to try to make one the same way this is very nice

Hey, I am impressed with this and I would like to try to make same cube, but I have one question; what is with the power supply? Do I need an external one or is the arduino enough? (If I am not wrong, arduino can deliver around maximum of 400mA and I don't think that is enough for something like this.) I want to build same one as yours. Best regards.

Hi!!. Very good way to handle the matrices and layers to achieve the individuality of each led. Thanks for sharing the project.

I also love this project! I got all the parts but was wondering, Can this be done with 3 color LED's? I am still learning the code, so there may be a few bug when I get done. Could you send me the complete code also, Please? My email is bnplu@comcast.net Thank you for the wonderful project and a Learning experience!

Hi cool project. I'd like to do something similar to this. I have 2 questions though. 1. Did you do research on ls (ttl) and hc (cmos) series comparability? Is this stable and always work well? 2. Is it ok to connect led directly to the ic (74574) without transistor?

Marcazzan_M

Hi, I have made one error, I use an 74HC138 not an74LS138, but in this case TTL and CMOS' compatibility it isnt't neccessary because I use the signal of the 138 only as a clock not as a voltage level. No, transistors are fundamental otherwise how can you control the single layer? If you don't use the transistors (with my schematic) the result is 7 equal faces.
