LED cube project Answered
Hey guys ,so was in progress of making the https://www.instructables.com/id/LED-Cube-4x4x4/step7/The-controller/ and i'm stuck on the controller step, a lot of people ware stuck on this as I see from the comments, and I can't find any help, would someone mind helping me? I have several questions, if you have time, I'd appreciate it if you answered them!
after zooming into the drawing,
few questions remain:
- resistors for the cathode and anodes, what resistance should they be? I'm powering this cube with 5.7v 1800ma nokia charger, current LEDs of mine run with a 120k ohm resistors, would these do fine?(connecting to the chip)
- On the left hand side, what are the 5V + > , GND connection mean to do? do they connect to the cube? or?
- also the connection 18-21 that have resistors and then are linking up to... cant read the writing, im guessing it should be the anodes as thats the forward current?
Hope someone could answer these for me? THANK YOU so much!
After i'm done making this project I will hopefully be able to make an easy to understand diagram for newbies like myself so they can work out this circuit themselves and wouldn't give up
