1  Using Arduino / LEDs and Multiplexing / Re: Led Cube 8x8x8 on: December 05, 2012, 05:19:11 pm
Sorry for the late reply. we are useing 74hc595n shift registers, the positive leads are connected in columns down the cube and the negatives are connected in layers. We are trying to use a 64-bit binary pulse from an arduino uno to turn on the leds. We also have access to the arduino leonardo and arduino due. Can you please also clarify on the 8 N-channel MOSFET.

4  Using Arduino / Audio / simple audio input for arduino on: October 11, 2012, 01:42:50 pm
I am in grade 10 electronics and have some experiance with arduino. I am trying to make an equilizer that resembles this (skip to about 1 min) but i cannot get any audio input readings. When i try to get readings with a mic i get 358 and it doesnt move or it shorts and hits 1023 which is max. I am trying to get a rate between 0 and 1023 that goes up with the loudness of the sound. PLS HELP.
