thanks for the reply guys..
as I said Im new. so the 'why' questions should be self-evdident. =)
just dont have the knowledge/experience to know better/different.
ok.. so I will go back and add in the
-
10nF cap (103) in front of the vRegulator (across the GND and OUTPUT) BEFORE the power +/- lines reach it.
-
22uF cap across the 'rails' on my breadboard.. (after the GND/output from the vRegulator)
I guess Im more confused by your comments now?
I see/added in the two missing caps..
but there are two more? seems like I have 4 missing components from your comments
also this:
"You should really have a current limiting resistor in series with the LED - you're going to damage the LED or damage the output pin wired up as it is."
not really that far along yet.. =(
(knowing how to correctly wire up the leds/components for testing/development.. I really want to get to the code parts of playing more) LOL
I thought the chip was capable of turning on smaller accent leds types without much fV and low mA?..
(but what do I know).. I never know if I have things wired up right/wrong..
to be clear I put the + lead to the chip/pin always,.. and the - to the GND rail..
(not other way around)?
where does the resistor go? between I/O pin and + lead from led?
Thanks Lefty, FCrossroads..everyone for replying/helping out.
appreciate it. =)
