LEDBlinky + LED-Wiz... will this do what I want?

<< < (2/2)

SpatzST:
What do you mean by 80 connections? EDIT: Oh you mean 20 additional ground wires, right?

Each LED-Wiz is 32 outs, so I can get two, for a total of 64 outputs, of which I'll use 60 (rgb for 20 buttons), and maybe somepoint down the line light up coin buttons or something for the remaining 4.  Will I need anything else? Additional power supply or is USB power enough?

dkersten:
I can't answer the power supply question because I don't use the LEDWiz.  But yes, the extra 20 connections are ground (or +5v, depending on the type of LED).

SpatzST:
Well, I pushed the button (bad pulled the trigger pun).  20 Electric Ice 2 buttons with the Helio9 LED's, two LED-Wiz's, and some terminal connectors to clean up the grounding wires.  Now we wait, anxiously.. very very anxiously.

They would be +5v wires.  Pretty much all RGB LEDs used in this type of application will be common anode, AKA +V.  Just wanted to make this clear to save folks from needing to re-wire things if they get it wrong :)

As you will be using 20 of the Helio9's, you will definitely need external power (i.e. from your PC supply.)  But I think you will find them to be well worth that little extra effort when you see how bright and colorful they are, even in a well lit room. ;)
