196  Forum 2005-2010 (read only) / Interfacing / Re: LM34 with an 8x32 LED Matrix? on: September 16, 2010, 08:22:26 pm
Here is more info:
Matrix: Sure Electronics Green 0832 LED Matrix 8*32
Arduino: Arduino Duemilanove
Thermistor: LM34
What I want to do: Connect both the thermistor and the Matrix to the Arduino and have them interfaced to each other.
What I am asking: What pins do I connect and what script do I use?

Does anybody know how to interface an LM34 with an 8x32 LED Matrix?

Yes I have the manual in front of me. I am trying to figure out how to connect my arduino with my led matrix. Can you explain it to me like this Digital GND goes to port ___ on the led matrix.

Sorry to bring back this post but my LED Matrix came today and I have been trying for hours to figure out which pins on the Arduino Duemilanove go to which port on the ribbon cable on the Matrix. Does anybody know?

Hi I am a complete noob as you can probably already tell by my post count. I just got my first Sure 0832 and an Arduino Duemilanove. I noticed on all the pictures and videos that people have wires connecting the Arduino to the led matrix. Where do I get those wires and how do I connect them from my Arduino to my Sure 0832?

I have a Arduino Duemilanove ATmega328

205  Forum 2005-2010 (read only) / Exhibition / Re: LED Matrix Spectrogram on: September 10, 2010, 09:57:49 pm
(Tested on windows 7)

1. Click the Start Button, type "MMSYS.CPL" (without quotation marks) in the Start Search box and press Enter.

2. On Recording tab, right-click on the blank area

3. Check “Show Disabled Devices” and “Show Disconnected Devices” and the Stereo Mix should show up.

 

If it is disabled, right click on it and choose Enable.

Hi, I am trying to get your spectogram up and running on my 0832 Green LED Matrix. It compiles and uploads fine to my Arduino. The PC Application launches fine but no leds are lighting up. Why is this? Im using Windows 7.

209  Forum 2005-2010 (read only) / Frequently-Asked Questions / Re: XML Feeds on: December 29, 2010, 06:54:36 pm
I now have a feed at http://www.google.com/reader/atom/user%2F15916171905404598697%2Flabel%2FArduino

I need help with this part of code:
Code:
  // Find specific tags and print data
      if (matchTag("<temp_f>")) {
            Serial.print("Temp: ");
         Serial.print(dataStr);
      }
      if (matchTag("<relative_humidity>")) {
            Serial.print(", Humidity: ");
         Serial.print(dataStr);
      }
      if (matchTag("<pressure_in>")) {
            Serial.print(", Pressure: ");
         Serial.print(dataStr);
         Serial.println("");
      }
How can I extract the text of each emails subject line as they all have the same tags which in this case is <title type="html"></title>.

Currently also I have the feed displaying more than just temperature. How can I extract only the temperature and nothing else?

Yeah, ignore the other post. How would I display the Current Time though?
