Arrch


then show me the parts, which resistors.. i learn when i am shown and taught the right way.. don't just say go get "resistors" but not tell me which one.. that's no help at all!

i have leds, but they don't tell me anything about them..


Well, typically components come with datasheets, so I would start with that...

and one learns from that? good job teaching.. not!


You're expecting me to teach you? Did the tuition check you sent me get lost in the mail?

ok, lets start from the beginning...
do you know how to connect a led to the arduino and to code it so it turns on and off?


obviously


haha not so obvious from your posts.

So what you know to calculate the resistor based on the led, or you just get a random resistor and led?

You have a RGB led, and there is a RGB sketch at your disposal in the examples, try it.
Start with one, get it to work, then add more. Your resistors should be no more than 150 - 200 ohms.

TFT_Extension, OneWireKeypad, SerialServo, (UPD)WiiClassicController, VWID

I'm a really good teacher.
I teach people to SCUBA dive.
I haven't yet lost a pupil

Of course, I weeded out the ones who didn't want to learn before we even got wet.


You really need to be a good teacher to teach SCUBA dive, same as skydiving and all of this sports.
Trust me, you teaching skills are not the problem here hehe

i got a bunch off ebay.. no data - they were just rgb 4 pins.. came in a clear bag.. so, no i did not know how many i needed. i learned later on that i would need 3 resistors per led (still don't know which ones). then later on i needed i/o pins (never shown to me, so i don't know what to get).

so i'm to learn without being shown? nice way to teach a new person..
