Arduino circuit/breadboard not working at higher voltage?

wow..

I barely understood much of that (sorry) I know your trying to help/educate me int he best practices.

That schematic looks foreign to me so far.. =( although I do understand the D13/P19 reference..

(Im trying to stick with it.. once I do things a few times/repetition.. I understand and feel comfortable..just not there yet) =(

here is the 'fix' I did on both breadboards to stabilize my vRegulators on my projects:

looking at the schematic (again)..

Im thinking you mean the RIGHT side/box/object for 19 (PB5).. not the one on the left? since it goes nowhere?

although I have no clue how to tell or see there is a 'series resistor'...

matter of fact the more I look at the diagram/schematic.. the more Im getting lost.

so to swing back on topic..

I do 'not' see or understand these 'large caps' why or even placement.. vs the caps I just put in place per Leftys suggestion and cobbling it together from the links.

is what I did wrong?

thanks
