I'm quite sure it was not damaged, as it was lit all the time it was connected like this. Any ideas? Is this an LED, and is that the cheapest way to make a remote sensor (by wire) remote to the remote receiver module itself?
2  Using Arduino / Sensors / IR receiver on: March 13, 2011, 05:54:35 am
Hi all,

I have a power meter that blinks via an IR LED. I also have an IR receiver (from a microsoft media center remote system, the 3.5mm jack type). I've been trying to use the receiver with the IR signal, but do not know exactly which type I have (two leads). During trial and error, I found that once it was powered in reverse, it lit up with a visible red light. Does this mean I have a LED and how do I read signals from this?

As far as I remember, the Raymarine plug can comminucate on SeaTalk or NMEA. At least on the st1000 tiller pilots.

5  Using Arduino / Programming Questions / Groundlab GSM Library with newSoftSerial on: February 05, 2011, 06:53:00 pm
Hi all,

I am trying to use my old cell phone for text messaging by using the groundlab GSM lib ( This is apparently made for the Mega, and when I try to substitute Serial3 with mySerial (as I usually do), I get these error messages:
SMS:19: error: no matching function for call to 'gsmSMS::gsmSMS(NewSoftSerial&, long unsigned int (*)(), HardwareSerial*)'
C:\Programfiler\arduino-0022\libraries\GROUNDLAB_GSM_ARDUINO/gsmSMS.h:32: note: candidates are: gsmSMS::gsmSMS(HardwareSerial&, uint32_t (*)(), HardwareSerial*)
C:\Programfiler\arduino-0022\libraries\GROUNDLAB_GSM_ARDUINO/gsmSMS.h:25: note:                 gsmSMS::gsmSMS(const gsmSMS&)
Is there any way to get this library to work with NewSoftSerial, or am I going to have to buy a Mega?

You were right. I moved an array into a function (was not needed outside) and it worked. It's easier to find the fault when you know what to look for...

Hi again all,

I am trying to combine two of my sketches that work well alone, and the combination is not that complicated. The strange thing is that it works from time to time, but then suddenly one or all three variables for the temperatures are lost, indicating anything from -1500 deg C to 3000 deg C! The variables are locked inside an if and a switch case, declared as 0 and updated every 10 mins from a serial event, but suddenly they are out of control. It doesn't sound like a memory thing to me.
Has anyone seen anything similar, in general terms?

I got it working again, by making the switch to 0022 and deleting and downloading the library again.

9  Forum 2005-2010 (read only) / Troubleshooting / NewSoftSerial not working for me anymore on: January 15, 2011, 05:57:33 pm

I have been struggling for a few days to read some serial info from an rs485 network, and I thought it was my ttl conversion chip setup that was not working properly, but I have tested with an ftdi cable and I get perfect readings. Why can I not read the same into the arduino?

The sketch I have been trying is based on the simple example, and simplified even more:
#include <NewSoftSerial.h>

NewSoftSerial mySerial(6, 7); //rx,tx

void setup()  
  Serial.println("Goodnight moon!");
  // set the data rate for the NewSoftSerial port

void loop()                     // run over and over again

  if (mySerial.available()) {

It should read strings like:
41 00 00 00 DF 17 20 83 08 4F 6B C7 08 6B
(hex or not is not important at this stage, I'm trying to find the fault)
but instead it's dead silent.

Is there a reason why the library example used two different speeds for mySerial and Serial?

Try changing the baud rate to what the sketch uses, this usually helps...

11  Forum 2005-2010 (read only) / Bugs & Suggestions / menu items in separate columns on: January 17, 2011, 07:38:51 am

I am loving Arduino su much I have more libraries than the single column will fit. I would like to see as many columns as necessary for examples and libraries in the menu.

12  Forum 2005-2010 (read only) / Bugs & Suggestions / Easier comment / uncomment in arduino IDE on: July 10, 2009, 07:05:14 am

Thanks for a wonderful IDE and board. I have looked at the Processing IDE which is very similar, and thay have this nifty comment/uncomment right click choice. Would it be an idea to implement this in Arduino IDE, so that you can mark several lines and insert // before the line? It would certainly be easier to debug with this feature.

Exellent. Yes please, i would love to see your code

Hi all,

Does anyone have a working example of a get function for pachube (remote input to arduino from a pachube feed)? the one I have seen on the pachube tutorial is both get and put, but I have not managed to separate the get call.
