1  Using Arduino / Project Guidance / Arduino Cell phone repeater / signal booster on: March 13, 2013, 02:31:58 pm
I would like to build my own cell phone repeater or signal booster and I was wondering if any one had tried this.  I have no idea where to start or if this is even possible. 

Any help would be great

If I wanted to use the below sensor with my arduino, how would I link it with my arduino?  Is there some kind of tutorial?  Will the only thing I need is an xbee system?

The only problem is that both of those sensor go a lot farther with 5.5v.  So there range is dependent on the voltage that they run on.   I would like to the the extra distance.

Things like ultrasonic censors, PIR Motion, lazors  stuff like that

the arduino comparable sockets run on 3.3v and I need them to run on 5v.  That is the problem with this board.

the Seeeduino Stalker has got to be a perfect board but the only problem is that the I/O ports run on 3.3v  I need them to run on 5.5v.  Below you will find a link to the wiki on the Stalker, with schematics.  What can I remove on the board it self to make it run on 5v.  I see on the schematic that 5v is coming in but by the time it his the microprocessor it is 3.3v.

Also does any one know of an arduino compatible board that has similar features that the Stalker has?

Surprisingly there is not a lot of information about controlling your house lighting with arduino.  My goal it to control my house lighting with my arduino and have the manual switches still work.  I also want to know the status of the lights.  I am having some serious trouble figuring out how to do this.  My first thought is it might have to be wireless because there are a few light switches and having a board at each switch does not sound efficient.  Dose any one have any ideas or experience to help me get started?
8  Using Arduino / Programming Questions / Creating an array on: May 27, 2012, 10:18:14 pm
I have to work with a lot of numbers and I need an array that has all of the numbers from 0 to 1500.  I want to have some kind of loop that can be defined int the "void setup" function, that will set up the desired array.  I was thinking that I could make a "for" loop just keep adding all of the numbers until it hits 1500.  Obviously that did not work. lol   Bellow you will find one of my attempts to try this.

Any help would be great.

const int MaxChars = 1500 ;
int temp[MaxChars+1] ;

int array[] = {1, 2 ,3, 4, 5} ;

void setup() {

  for ( int j = 0 ; j < MaxChars - 1 ; j++ )
    int num ;
    for ( int index = 0 ; index < MaxChars - 1 ; index++ )
     temp[index] = num;

void loop() {

for  ( int i = 0 ; i < MaxChars ; i++) {while (i < MaxChars ) {Serial.println(temp[i++]);}}
