How about a parallel in shift register? Idk how fast one can be clocked but it would probably work to get the byte
idk anything about that board or cameras,  so I can't help with anything else really, but a shift register is fairly easy to use,

heres a project ive been working on a while
a car controller that so far has connections for 4 relay channels, 4 pwm channels, 3 temp sensors, a 2.8 in tft touchscreen, 2gb accessablew sd for datalog, voltage and current sensor, nrf24l01(future)

i have a shield in the making for easy connections on the inside as well as wireless for idk what yet, not coded for
i have a dedicated atmega328 on the shield to do some realtime led channels beating to the music from a msgeq7, so three led channels for lows, mids and highs

Save money and buy just what you need separate, I usually buy my arduino boards and components off ebay,
an uno is like 20$ free shipping
Leds, diodes, pots,, all you can get really cheap free shipping
Ebay also has a bunch of shields, but usually for that id buy from an actual online store

Get rid of the 5 second delay, it does nothing for those 5 seconds? If you move the joystick back it will just stay lit

How mobile is your project? Does it stay still at all? Maybe you could get away with a small solar panel on top that would charge a battery or help lessen the load atleast, assuming your load is about 200ma, this would almost power it entirely or atleast charge a battery

Your explanation seems a bit confusing, but I guess you mean controlling the bightness of a series of leds by communication with a computer?
that is definetly possible and quite easy,
look into pwm, as well as serial communication

First did you notice how any number that it gives is both > 0 and < 355? They both ring true and do nothing or flash real fast,
depending on your goal you could find the absolute value from 160 then map it to the pwm range,
like
Val = sensorvalue - 160;
val = abs(val);
Ledpwm = map(val, 0, 160, 0, 255);
analogWrite(6, ledpwm);

And maybe add something to smooth out the jitters for a smooth led that changed brightness depending on the position, even maybe multiple leds that light up in the direction moved

Or do something less variable
If(sensorvalue > 160){
digitalWrite(13,1);
}
if(sensorvalue < 160{
digitalWrite(13,0);
}
 This is probably the most simple
1586  Using Arduino / Project Guidance / Re: interface with vex? on: November 12, 2011, 06:47:24 pm
Thank you, your googling skills are definetly better than mine lol
i did search some,  not too deep and I read abit about ppm and how it works, which is wat I believe it uses, but I have no clue what the reciever module puts out and how to read it
I was hoping somebody tried this before me and would have either a great example or great resource
I don't have a logic analyzer or oscilloscope to use, so figuring it out myslef would probably not work and just blow up the module
Sorry if I seem unwise in the ways of searching but I do understand the idea of finding the answer yourself which is why I offer myself up to the forum gods in a pitiful plea for guidance, a yellow brick road to the holy grail of answers and a plethora of easy to examine example of which I can use to the advantage of furthering my knowledge without blowing up the one module I have that I am using as a cheap( I already have it) and extensive controller
lol thanks for any help
1587  Using Arduino / Project Guidance / interface with vex? on: November 12, 2011, 04:29:47 pm
Idk if anyone has ever heard of vex before, but does it seem possible to use a vex reciever with the arduino? I have a real nice 8 channel remote for the vex and the reciever module that I want to use with my arduino
it is normally connected with a 4 pin connector so I would imagine vcc,gnd, and serial?
any help would be appreciated
Here's the module

O i get it, than you
1589  Using Arduino / Microcontrollers / Re: arduino share crystal? on: November 11, 2011, 06:58:01 am
So it is okay to leave xtal 2 of the second chip floating?
1590  Using Arduino / Microcontrollers / Re: arduino share crystal? on: November 10, 2011, 08:26:59 pm
I don't need to have them programmed at the same time, and I probably will program them before insertion into the project, and since I am buying them with the bootloader I will just use an uno board to program then insert into a socket
my plan would be to have the chips as close to each other as possible and have the crystal in parrallel to each, basically just to save space since they will be on a mega shield
If the datasheet says it can be used by another device then I guess no fuses need to be changed?
The reset line really is not needed in my particular use but I will have them wired to the reset line of the host mega just in case,
