is there such a thing as a digitally controlled pot?

i was just thinking about this when i came across this thread.

now is there no way because the arduino isnt currently capable (ie not part of the core code) if thats the case could a custom core be written.

or is there no way because of the technical limitations of the chip and execution enviroment?

and why limit it to fat if raw works fine?

this might be an incredably stupid question, but im new here.
(you can thank ladyada her GPS data logger kit got me addicted)

someone mentioned using the SD card as a 1gig EEPROM.
would it be possible to use the SD card as the storage location for the sketch code?

maybe in a dual core setup. using one arduino as the access medium to the SD card and then having the second arduino execute the resulting code from the first?

like i said probebly a really stupid question, but im still new, and a bit of a dreamer

if im understanding correctly, breakfast supports handshakes... right?

someone elsewhere had talked about the desire to connect an arduino to an iPhone, but someone pointed out the fact that the iPhone requiers a handshake to connect. Might this be a solution to that problem?

Thats a really clean implementation zackprice.

Im working on an RFID door lock, and iv already used 9 of the 13 digital pins.

Mind you this is my first "from scratch" arduino project so it probably not the cleanest way to do it.

im hoping to have to code usable/proto'ed in the next couple of days.
as for the hardware its mostly bread boarded but i still have some work to do on that.

i *REALLY* like your implementation and install

BTW do you get alot of JUNK data from the RFID reader? im getting alot of random junk from the RFID read when its sitting there (using the Parallax serial reader
http://www.parallax.com/Store/Microcontrollers/BASICStampModules/tabid/134/txtSearch/28140/List/1/ProductID/114/Default.aspx?SortField=ProductName%2cProductName )
its actively reading because i havent figured out how to activate the reader based on tag proximity yet

i think you mean "up up down down left right left right b a select start"  smiley-wink

true i hadnt thought about the clock difference.  but would it be possible to capture the signal on a laptop running 2.56Ghz if i could figure out some way to attach a 433Mhz antenna and read the incoming data?

this was supposed to be an "easy-ish" way to jump back into the world of arduino.  whoops.

all i need to figure out is the command codes prior to RF modulation that can then be programed into an arduino based system for later modulation and broadcast.  Maybe i should go back to digging through the net and see if i cant find them somewhere.

anyway guys thanks for the insight.

annnnnnnnd i have no idea how to do any of that.  so maybe this wasnt a good place to jump back into the world of arduino

LOL good point about drinking while working, fortunately I dont drink.

Like i said i know its a 433Mhz signal, and from what i have been able to research it doesnt seem that the signal is keyed to any specific unit. so i dont understand why i cant just grab the resulting RF burst and then just retransmit that.

Kind of like recording an IR signal to an audio wave form and then playing it back on an iPod with an IR diod wired for connection to the headphone jack.

Fairly green when it comes to developing and building with the arudion so i thought this might be a good way to get started.

I found a TouchTunes Jukebox for sale a while back.  I bought it with the intent of gutting it for parts, but being the music junkie i am i have now decided to use it for its intended purpose.

HOWEVER there is a catch.  The guy I bought it from had lost the remote.  Now instead of buying a new one I thought it would be fun to try and build one off the Arduino.  Maybe using the arduino is overkill i dont know.

Fortunately for me the bar down the way from me has the same jukebox with a working control.  What I would like to do is build something that would allow me to record the RF signals from the bar jukebox and save them (to a CF card or something [i have a library for that, came with a shield kit i bought a while back) or some other media) so that i can "play them back" for the jukebox i bought.

anyone have any ideas?
I know the frequency is 433mhz and i have found a few places to buy the antennas but how to hook it up and how to go about actually recording the signals, well im a little lost.

I would appreciate any help you all could give.
