Wow, thanks for that!

Question regarding HL1606, according too Adafruit (http://www.adafruit.com/products/306) "HL1606-based strips did not have PWM built in (they could only display 9 colors by default)"

Hello

Going to order some "Flexible LED strips" and Im wondering what the pros and cons are of the different controllers...
Maybe you guys with more knowledge can help?

I'll try to update the list

HL1606
  • -PWM

LPD6803
  • ?

LPD8806
  • +PWM

WS2801
  • ?

WS2811
  • ?

3  International / Hardware / Re: Alimentar Arduino on: July 05, 2012, 06:01:46 am
Me auto respondo.
No, no es posible ya que el voltaje de salida del transformador es en corriente alterna (AC) y no en corriente continua (DC), que es la necesaria para alimentar el arduino.

Disculpen las molestias.
Un saludo.

Hola,
Tengo una duda con respecto a la alimentación del arduino uno.
¿Es posible utilizar un transformador de 220v a 11.5v 4A como este (es el que se usa para las bombillas halogenas de las viviendas) para alimentar la placa?

Muchas Gracias
Un saludo.
5  General Category / General Discussion / Arduino UNO or Leonardo? on: June 12, 2012, 06:20:52 am
Hello, I was wondering which model of Arduino I should buy. I heard that Leonardo is newer but I don't know if UNO is better for learning Arduino's basic functions. Which Arduino should I buy?

Thank you very much, it works now smiley

I changed the the pin RX to one of those in the link you posted.
7  Using Arduino / Project Guidance / Serial Communication only works for UNO(not MEGA) on: April 23, 2012, 07:46:03 am
Hello!

The code example below have been working flawlessly on Arduino UNO for me, however, when it's put on Arduino MEGA 2560, it doesn't seem to work at all.
The code consists of two parts: the sender and the reciever. It's a quite simple setup consisting of one Arduino MEGA sending 'a' and 'b' continously through serial communication. The problem seems to occur with the other Arduino MEGA which is supposed to recieve the input and print it out in its own serial monitor.

Sender:
Code:
#include <SoftwareSerial.h>

#define rxPin 0
#define txPin 1

SoftwareSerial mySerial =  SoftwareSerial(rxPin, txPin);

void setup()  {
  // define pin modes for tx, rx, led pins:
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
  // set the data rate for the SoftwareSerial port
  mySerial.begin(9600);
  mySerial.println("Hello Board 2");
}

void loop()
{
  //continously send out 'a' and 'b'.
  mySerial.print('a');
  delay(100);
  mySerial.print('b');
  delay(100);
 }

Reciever:
Code:
#include <SoftwareSerial.h>

#define rxPin 0
#define txPin 1

SoftwareSerial mySerial =  SoftwareSerial(rxPin, txPin);

void setup()  {
  // define pin modes for tx, rx, led pins:
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);
  // set the data rate for the SoftwareSerial port
  mySerial.begin(9600);
  mySerial.println("Hello Board 1");
}

void loop()
{
  // listen for new serial coming in:
  char someChar = mySerial.read();
  // print out the character:
  mySerial.println(someChar);
  delay(100);
 }

I'm using Arduino 1.0, and you can see from the example above, i'm using the SoftwareSerial library.
First time I've posted on the Arduino board, so let me know if I've let anything out.

Thanks smiley

Android 3.0 (Honeycomb, intended only for Tablets) is a bit of a dogs breakfast and I think most people are hoping Android 4.0 (Ice Cream Sandwich, intended for best android Tablet and Phones) will sort that out.

Is there a git repository for the Time library?
10  Development / Suggestions for the Arduino Project / Update Library Tutorial for 1.0 on: December 31, 2011, 11:36:07 pm
In the "Creating a Library" tutorial, it says:
Quote
You need a couple of other things in the header file. One is an #include statement that gives you access to the standard types and constants of the Arduino language (this is automatically added to normal sketches, but not to libraries). It looks like this (and goes above the class definition given previously):
Code:
#include "WProgram.h"
In Arduino 1.0, WProgram.h has been renamed to Arduino.h, and the documentation should be modified as such.
11  International / Deutsch / Audio Prozessor TDA7318 am Arduino Uno on: December 23, 2011, 02:31:22 pm
Hallo zusammen

ich versuche gerade verzweifelt mit einem Audio Prozessor TDA7318 über den I2C Bus zu kommunizieren.
Aufbau: 2 Taster an digitalen Ports
Vcc vom TDA7318 an Vin
Gnd vom TDA7318 an GND
SCL vom TDA7318 an A4
SDA vom  TDA7318 an A5
DigGnd vom TDA7318 an GND

Sollte das soweit passen?

an Left in 1 hab ich einen MP3 Player angeschlossen.

Folgender Code:
Code:
#include <Wire.h>

#define audioControl 0b1000100
void setup()
{
  pinMode(13,OUTPUT);
  pinMode(3,INPUT);
  pinMode(4,INPUT);

  //Wire.begin();
}

void loop()
{
  if(digitalRead(3) == HIGH)
  {
    Wire.begin(audioControl);
    Wire.beginTransmission(audioControl);
    Wire.send(0);
    Wire.send(1);
    Wire.send(0b01011000);
    Wire.send(0b00001100);
    Wire.send(0b00001011);
    Wire.send(0b11010011);
    Wire.endTransmission();
  } 

  if(digitalRead(4) == HIGH)
  {
    Wire.begin(audioControl);
    Wire.beginTransmission(audioControl);
    Wire.send(0);
    Wire.send(1);
    Wire.send(B01010001);
    Wire.send(B00001100);
    Wire.send(B10001001);
    Wire.endTransmission();
}


Wenn ich die Tasten betätige sollte er ja umschalten.
Da mit im Moment noch passende Widerstände und Kondensatoren fehlen, hab mich meinen Kopfhörer im Moment an OUT(L) angeschlossen, sollte ja nach dem Schaltplan im Datenblatt direkt nach dem Umschalter kommen. Aber ich höre nur ganz leise ein Signal Aber es ist egal welcher Input geschaltet ist. Wo ist mein Fehler!?!?

Wäre nett wenn mir jemand helfen könnte...

Danke

Ok, then i will buy this:

You will need a transistor+base resistor, a small reed relay (5v, <40mA coil), or a logic level MOSFET to switch the LED on and off.

Do I need something further? Do I "transistor+base resistor, a small reed relay" just if I don't use a MOSFET. I don't need an resistor for my led, or?

Thank you very much!

Which Mosfet do i need. I find just some from 50V ... 100V ... etc. The lowest V is 50. Will this work or stands the volt for the used volts? Or for the max volts?

Will this work?

Thanks.
I want to built a ethernet remote control which will be mounted to the ceiling.
Will it switch fast enough for irda-signals?
