1  Using Arduino / Interfacing w/ Software on the Computer / Re: RGB controlling with processing,LEDS flicker on: December 23, 2012, 12:18:50 am
got the same problem here, try using the simpleanalog firmata sketch, that stopped flicker for me!

(sorry for my english!)

2  Development / Suggestions for the Arduino Project / Re: SAving the board type with the sketch in Arduino IDE on: December 05, 2012, 04:26:38 pm
agree! smiley-grin  working with uno and mega boards, (some attiny85 too), would be a nice add on, not essential but helpful

try changing the delay time!, in my case, (sony audio receiver) working delay time is 40 (not 100),
try other values as 45 (some samsung tvs) or 50...., the time between each command is important


Code:
int delaysony         = 40;

void loop ()
{
for (int i = 0; i < 3; i++) {
          irsend.sendSony(0x540C, 15); // Sony audio encendido
          delay(delaysony);
          }
}
/code]


Sorry for my english,  :D

 Añadele una memoria eeprom, añadele un sistema de energia extra (puede ser un megacondensador o una pequeña bateria que no necesita mucho tiempo de aguante) y cuando detectes que se va la tension el arduino lo sabe por medio de una interrupcion que habras programado, detiene el programa y vuelca en una eprom pequeñita, no hace falta mucha capacidad, los datos de donde se encontraba o las variables de tu invento.

Cuando luego vuelva la tension, el programa de cabecera lee si hay datos en esa eprom y si es asi y ve que no ha teminado la faena, salta a los parametros en que se quedo antes de quedarse sin energia y si no existe porque concluyo la faena pues no salta a ningun lado, continua procedimiento normal.

Un saludo.

Me sumo en un todo con eso!( sumando escribir un comando de "0" en la eeeprom, por las dudas para que en el setup del arduino controle, si el valor es 0 es una tarea nueva, sino, es una anterior que hay que resumir)

Otro mecanismo de seguridad para evitar errores de posición, es que al iniciar el código luego de una interrupción de energía, mueva los ejes hasta un tope para ver si los pasos del paso a paso coinciden con el ultimo valor del programa...

espero haber expresado algo que se entienda y sirva de algo (¿?) smiley-grin

Saludos,

Charlie
5  General Category / General Discussion / Re: Arduino Due (released Oct 22, 2012) Compatibility on: October 03, 2012, 07:42:08 pm
http://hackaday.com/2012/10/03/finally-an-arm-powered-arduino/

Far removed from the legions of 3D printers featured at this year’s Maker Faire in New York was a much smaller, but far more impressive announcement: The ARM-powered Arduino DUE is going to be released later this month.

Instead of the 8-bit AVR microcontrollers usually found in Arduinos, the DUE is powered by an ATSAM3X8E microcontroller, itself based on the ARM Cortex-M3 platform. There are a few very neat features in the DUE, namely a USB On The Go port to allow makers and tinkerers to connect keyboards, mice, smartphones (hey, someone should port IOIO firmware to this thing), and maybe even standard desktop inkjet or laser printers.

The board looks strikingly similar to the already common Arduino Mega. That’s no mistake; the DUE is compatible with existing shields, so connecting a RAMPS board for your 3D printer should be a snap.

Here’s a PDF (http://hackadaycom.files.wordpress.com/2012/10/due.pdf) the Arduino and Atmel guys were handing out at their booth. A few DUE boards have already made it into the hands of important people in the Arduino community, including 3D printer guru [Josef Prusa]. Sadly, the folks at Arduino didn’t think media personalities needed a DUE before its release, so you’ll have to wait until we get our hands on one later this month for a review.

more pictures....

setup:

atmega 2560 ---- touchOSC ---- Processing

2 rgb Led strips

2 UV Led strips

2 light dimmers

future ir control (trying to make it work right)
future voice control (Processing Voce library)
future temperature/humidity/light sensors...


send me a PM if someone whats some of the code (arduino/processing) or more info

(again sorry for my english)

first of all sorry for my english smiley-grin

made something like that for my home,

i live in argentina (220v here) and found some dimmer light-switches (capacitive ones) that got connection for a "slave" unit...

quick touch turns on/off
dimmers when holding....

closing the circuit between the slave and the Live wire works as pressing the key.... (mine is done with uln2803 and 5v relays)

got some pictures from my (up to now incomplete) setup attached,

8  Using Arduino / Microcontrollers / Re: ATTiny 25/45/85/2313 Pin numbers on: December 13, 2011, 10:57:28 am
Thanks for the replies.

However, I still don't understand why the physical pin numbers of these chips aren't used in the sketch like they are if you are using the 328 on the main Arduino board ?

look at the "cheatsheet" attached in my last reply, in the arduino board the pins are already labeled and traced to the headers so atmega328 physical pin 19 is Digital 13 in the board,  , (try looking at the front of the arduino pcb board and trace physical pin 28 to A5, that's the best way to "understand" the layout)....

p.d.: im a newbie too in this, sorry if i misunderstood something....
9  Using Arduino / General Electronics / Re: What kind of DC plug is this? on: December 13, 2011, 08:07:20 am
jonnyA:

in the link you attached, down the photos in the technical specs tab says:


Capacity: Input: 100V-240V. Output: 7.4V 2A
Dimensions: Cable reach approximately 5ft. Tip Size: 3 x .85 x 9mm
Condition: Brand New, 100% OEM compatible!
Type: AC Power Adapter Kit
Quantity: 1 Kit (Includes: 1 AC Adapter & 1 DC Coupler)

try searching for it (3 x .85 x 9mm tip size), hope you find it.

sorry for my english! (not as keen in writing as i should)

first time posting smiley-grin

found this "cheatsheet" (akafugu.jp) with pinouts of some atmel micros (pin 5 in attiny x5 shows as pb0) hope you can use it.

please sorry for my english, it's not my main language.
