Hi:

This is an Artificial Horizon/Compass combo built with Processing to be used with Arduino for 3 axis position visualization of a static swivel platform. It's not intended for navigation. At this point, the variables are dependent on the mouse position for testing purposes. These are part of the set of instruments I'm building to be used with Arduino. The idea is to have several "off-the-shelf instruments" already built to facilitate the implementation of Arduino projects using a computer.

Did you return already?
Posting the schematic will help.
214  Topics / Science and Measurement / Control Panels for Arduino/Processing 1.5.1. on: March 31, 2013, 09:43:02 am
This is a set of instruments and controls panels which can easily be configured to build several Arduino Projects in a relatively fast way. Still some coding will be required depending on the particularities of each Project; but having these Panels already built, will make the task way easier and faster. This Project was built using Processing 1.5.1.
More Panels can be added in the future such as Timers, Voltmeters, etc.

Suggestions appreciated.
Thanks.

Here is his post translated to English:
Hi:
" I'm beginning with Arduino and I don't know how to program the connection to an XBEE 1. If anyone knows how its done please let me know. I need both the sending and receiving code.
My project is a DS18B20 connected to an arduino and an XBEE. I need to know how to programn that."


Hola:

Es muy probable que muy pocos en este forum respondan a tu pregunta en espanol. Yo no he trabajado con el XBEE; pero te recomiendo que hagas una busqueda en Google y aqui en este forum y quizas encuentres algo. Tambien es muy probable que lo que encuentres este en ingles.

Si sabes algo de Ingles, aunque sea poco trata de hacer tu post en Ingles y enseguida te responden. si quieres yo te puedo ayudar un poco con la traduccion aunque mi tiempo es muy limitado.

Buena suerte.

Glad you solved.
Good Luck.

I don't knoiw much about bread boards as I never use them, I prefer to solder to avoid faulty contacts, etc. Anyways, is there continuity between the rails where you have your battery connected and the rail where you connect the power fromn arduino?. In the pic it looks you have plugged the battery into different rails. Try plugging the battery to the same railing section where all the other wires are.

On Processing:

//Define your variables here
import processing.serial.*;                 //imports serial library
int Com=0;                                         //Sets which Port from the list will be used.

void setup()
{
size(Width,Height);
frameRate(30);
blah; //whatever else you may need here.
blah;//whatever else you may need here
CPort = new Serial(this, Serial.list()[Com], 115200);              //Define CPort and baud rate here.
SendOrderToArduino();
}

void draw()
{
blah; //Your things here.
blah;
blah;
}


void SendOrderToArduino()
{
if(you want motor to move left==true)
{
Order=5;
}
if(you want motor to move right==true)
{
Order=10;
}
CPort.write(order);
}


On Arduino:
void setup()
{
blah;
blah;
Serial.begin(115200); //begins serial Communication with computer at 115200 bps.
}

void loop()
{
CheckOrder();
}

void CheckOrder()
{
if(Serial.available()>0)
{
Order=Serial.read();
if(Order==5)
{
MoveMotorLeft();
}
if(Order==10)
{
MoveMotorRight();
}
Order=0;
}


221  Topics / Science and Measurement / Data Logger & Recorder (Arduino UNO + Processing 1.5.1) on: February 24, 2013, 11:38:29 pm
Hi:

This is a Data Logger and Recorder built for trainning purposes using previous experiences with Arduino and Processing.  Still has some minor problems; but I'll leave it like that for now as my time is very limited and I'm kind of tired by now.

Input signal is connected directly (no amplification) to any of the Arduino analog inputs. User can select input channel from the computer screen.

here are the details: http://www.adrianelectronics.com/index.php?p=1_43_Data-Logger-Recorder

Thanks.

223  Using Arduino / Audio / Audio Animation (Arduino + Processing) (Completed) on: February 11, 2013, 12:53:30 am
Hi:

While working in my main Project I found some kool figures could be generated by using the Ellipse Equation with Processing. I posted in the forum tying to get some one motivatted to animate the figures as my time is really limited. Since no one did it I resolved to do it myself.

Using:
-Arduino UNO to sample the analog audio signal and send it to the computer via USB.
-Processing 1.5.1.

Features:
- Real time signal processing and dispaly. Figures on the computer screen are animated in real time using the audio signal.
- User can select any of the Arduino analog inputs from the computer software.
- Arduino is powered by USB only.
- 23 different figures can be animated (so far). User can select random sequence in which the figures are displayed, a preselected sequence or manual  selection.
- User can select show time (from 0-10 sec) for each figure when in automatic sequence either preselected or random.
- User can select the "speed" at which the figures "dance" (frecuency response of the System).
- Processing code about 900 lines.
- Arduino code about 2KB.
- Communication is bidirectional using numbers only (no strings). Arduino receives orders and sends data. Communication must be fast for real time data acquisition.

Here is some of the math and code:

Well thanks guys. This is to help a friend and he was going to pay for the boards. I think he is backing off now. Let's see if he says Ok I'll be contacting you. For now I don't think he will.
Thanks.

If the thing is battery powered and you use alluminum you just need to connect your ground to the chassis, like they do in cars. The 2x2 ft dimensions will be Ok with the bords I mentioned and the 10 pounds weight. They can hold more than that if you place them vertically. Like this []
