1  Using Arduino / Interfacing w/ Software on the Computer / Re: multi-purpose project, storage arduino info on ARM device on: April 01, 2012, 09:14:05 am
Hello Graynomad.

Greath, seams like you understood what i wanted smiley
I have looked at the Arduino MEGA 2560 - R3, seams like its going to be that board smiley
More easy, than using an Arduino UNO with a lot of Shift Registers smiley

Thanks for reply.

Okay.

Hmm, as i see it, im asking how to program the arduino board, and choosing an board with enoughf I/O (pins) to do the project, and how to program the arduino board from a device, so i can store infos from sensors on a default board (such as raspberry PI)

smiley Thanks.

Okay, im not sure if i got the right forum, or category, but here's one of the many projects.

I want to make a project that can be used for many diffrent projects.

The main goal is to communicate arduno with the Raspberry PI board that im getting soon, But, the problemes comes at the arduino part, i want more I/O (Pins) on the arduino board than what the Arduino Uno can offer.

I need to control at 4 DC step motors (With home-build H-bridges), a couple of sensors (Humidity and Heat sensors, even light sensors (LDR)), and at last, some relay's (4 relays should do it!)
So im kinda expecting 32-40 I/O (Pins), more would be nice to!

The sensors should write to a text file, on the raspberry PI board (Witch runs linux i hope), the more advance part is that i should be abel to write a command from a terminal from far distance, that can control the motors/relays on request.

The qustion is how to catch the project at the right angle, so i make this come true for me.

I know the following:
The raspberry board has some USB ports, so i can make it wireless via the ethernet, so i can set it up to an router, and then on the net, that part is easy enoughf. Making some of the Arduino code is not that hard eather. The hardware is almost easy for me to.

The problem comes at storing the data from sensors on the raspberry board.
I've never worked with that big of a project, but almost every of my big projects, requires this setup for working.

Im looking forward for responces.
Thanks in advance, and sorry for bad English.

Hello.

The idéa was to take a jack input, and then with some pot-meters/variabel-resistors on the multiplexer to the arduino, to fx. pitch or speed-up the sound.. Or whatever that can be done smiley

Regards.

Oh, sorry for the misplacing of topic.

Hmm, i want to make some kind of pitch in start, and whatelse you can do with arduino uno boards and programming smiley

Hello.

Could anyone show me a simple way to manipulate sounds with arduino and the 4512 chip?

The idéa was to take this chip, and also making a input and output channel for sound/jack-plug..

Anyone?

Thanks in advance, im allready a little lost on the searching area, couldn't find anything.

regards.

Hey all.

Thanks for reply and sorry i didn't reply befor now.

I think its just best i tryout the basic stuff first... smiley

8  Using Arduino / General Electronics / Saving data to a real Harddrive on: July 06, 2011, 08:14:42 pm
Hello Arduino ppl.

First i would like to know if it's posible to save data (fx. temperature data, distance data and so on), on a real harddrive from arduino?

The reason im asking this, is because, if i wanted to make a robot some day, it would help me a lot to save the data the sensors recive for both statistic use and for helping the robot to "learn".

Anyone that can tell me if thats posible?

Hey Paul.

Thanks for reply.

Can you code PHP? If yes, a little code would be greath :-)
Cause im not sure i understand what you ment.

Thanks again

11  Using Arduino / Interfacing w/ Software on the Computer / Re: Some wierd "Error" when using serial monitor on: June 19, 2011, 07:55:47 am
How esactly do i do that in code?

How should the script look like?

Thanks for the reply.
12  Using Arduino / Interfacing w/ Software on the Computer / Some wierd "Error" when using serial monitor on: June 19, 2011, 07:44:49 am
Hey.

First of all, i would like to say that the same "Error" comes on both my computers.

The arduino code looks like this:
Quote
#include <Servo.h>

int minPulse = 0;
int maxPulse = 180;
int center = 90;
int sdata;
int rater = 2;
int newPos;

Servo servo1;

void setup(){

  servo1.attach(9);
 
  Serial.begin(115200);
  Serial.println("Vi begynder her.....");
  Serial.println();

}

void loop(){

  if(Serial.available() > 0){
 
    sdata = Serial.read();
    Serial.print(sdata);
   
    do
    {
   
      if(newPos > sdata){
       newPos = newPos - rater;
      } else {
       newPos = newPos + rater;
      }
     
      if(newPos > maxPulse){ newPos = maxPulse; }
      if(newPos < minPulse){ newPos = minPulse; }
     
      servo1.write(newPos);
     
      Serial.print("Motoren er paa: ");
      Serial.print(newPos);
      Serial.print(" og forsoeager at ramme ");
      Serial.print(sdata);
      Serial.print("\n");
      delay(1000);

    } while(newPos != sdata) ;
   
  }

}

The problem is, when open serial monitor, and what ever you type, it will change the number you entered, then it changes it to 49....


What is wrong with this picture?

Thanks in advance.
13  Using Arduino / Programming Questions / Serial programming and php on: June 18, 2011, 10:45:47 pm
Hey Arduino people.

Im doing a big project in my home, and need to control some servos, from my php work.


How do i do that?
Im using a php_serial.class.php

And are not sure how to use it.

Btw.. Could not post the code here, it's to long.
14  Using Arduino / LEDs and Multiplexing / building your own multiplexer on: June 06, 2011, 01:19:44 am
Hello ppl.

Im looking for a way to build this board from the bottom:
http://www.sparkfun.com/products/9056

Anybody that know a little about that? Witch multiplexer IC i should use? I've been looking at this multiplexer:
http://viewitem.eim.ebay.dk/CD74HC4067E-CMOS-Logic-16Ch-MUXDEMUX-74HC4067/300559049062/item

But are unsure how to make the connections from the arduino uno to the multiplexer, and then further to my sensors.

Any help?

Thanks in advance.

15  Using Arduino / Sensors / Re: 35 pcs LM35DZ and arduino uno board, how to? on: June 04, 2011, 10:25:58 am
Hello and thanks for reply'in.

I might be abel to get them in Denmark, but we have some strange taxes, so i would like to build it from scratch if you understand?

Found this:
http://viewitem.eim.ebay.dk/CD74HC4067E-CMOS-Logic-16Ch-MUXDEMUX-74HC4067/300559049062/item

Now i just need to know how to build the rest... smiley
