I will get it. When I do get it though is there a chance that I could fry my arduino?
32  Using Arduino / Programming Questions / Re: Virtual switch on: July 24, 2011, 03:47:45 pm
By searching that I found a Triac-output, 400V optoisolator. 6-pin DIP package at allelectronics: http://www.allelectronics.com/make-a-store/item/MOC3022/OPTO-ISOLATOR-TRIAC-OUTPUT/1.html

That will work right?

Datasheet here: http://www.alldatasheet.com/datasheet-pdf/pdf/27237/TI/MOC3022.html
33  Using Arduino / Programming Questions / Re: Virtual switch on: July 24, 2011, 03:16:03 pm
What are the specs that I need on the optoisolator for this to work. I will go to all electronics today and compare the selection to the specs and buy a few. All Electronics has the following on there website:

NPN transistor output. 6 pin DIP package.
NPN darlington output. 6 pin DIP package.
Would any of these work?

When I went there previously they had a few more in store than they had online.

I know how to use google. I want to get the optoisolator from All Electronics as it is 5 minutes from where I live.
35  Using Arduino / Programming Questions / Re: Virtual switch on: July 24, 2011, 02:53:04 pm
I cant seem to find that at the Allelectronics website.
36  Using Arduino / Programming Questions / Re: Virtual switch on: July 24, 2011, 02:03:50 pm
I should have stated this in the beginning but the flash is a disposable camera flash and the idea is just to make a high speed photography trigger with the parts available at www.allelectronics.com. What parts would I need? I was thinking of using this:
but I cant find a Opto Isolator at All Electronics that works.

So instead of http://www.allelectronics.com/make-a-store/item/RLY-648/5-VDC-DIP-RELAY/1.html what relay do I get from all electronics?
38  Using Arduino / Programming Questions / Re: Virtual switch on: July 23, 2011, 07:43:13 pm
Yes.
See the Learning or Playground section for accepting Serial input.
Use a relay like this to close the contacts
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=PB1110-ND
http://media.digikey.com/pdf/Catalog%20Drawings/Relays/FX2%20RELAY%20NON%20LATCHING%20FTPRNT.jpg
Connect one side of the Coil to +5V (Pin 1), the other (Pin10) to one side of a 15 ohm resister, the other side of the resister to an arduino output pin that you will drive low to energize the relay (and you may not need the resister, but start with it). Put a diode across pins  1 (cathode) and 10 (anode) to voltage spikes away from the arduino pin
(such as http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=1N4004FSTR-ND).
Connect pins 4 & 5 to your contacts.

Will this work using my relay that I bought? If not can you please explain the schematic

I have now the following:

http://parts.digikey.com/1/parts/753815-relay-mini-dpdt-2a-5vdc-pc-mnt-ds2e-m-dc5v.html

A diode that appears to say "16".

How would I hook these up to create a virtual switch?
40  Using Arduino / Programming Questions / Re: Virtual switch on: July 22, 2011, 12:02:50 am
All I need to do really is touch two wires together momentarly. The problem is it is needs to be triggered by a left click as the program I am using converts sound into a left click
41  Using Arduino / Programming Questions / Re: Virtual switch on: July 21, 2011, 11:59:42 pm
Is there anyway I can do this all without external hardware?
42  Using Arduino / Programming Questions / Virtual switch on: July 21, 2011, 11:35:57 pm
I have a camera flash that is triggered by putting two wires together. Is there any way to trigger that by plugging the wires into my arduino duemilanove and typing something into the serial monitor? It will need to be triggered my a left mouse click.
43  Using Arduino / Project Guidance / Re: 56k IR Reciever with Red/Yellow/Green Indicator on: July 13, 2011, 08:20:56 pm
Yep, that is how I got this info. What I really want to do is have  3 sets of 22 led's powered by a 9 volt battery. Each set will bes used for light painting so all the receiver is really doing is switching between the sets when signaled by a Apple Remote. If this is not possible I will use the Ir switch to turn the battery on and off, and manually switch between sets.
44  Using Arduino / Project Guidance / Re: Independently control 25 RGB LEDs on: July 13, 2011, 07:51:34 pm
You might be interested to know you can now get RGB LEDs in strip form complete with driver chips that allow individual control via some sort of serial interface to every LED - not cheap, but then 32 RGB leds aren't that cheap anyway - looks interesting and might be
useful for this project:

And as a bonus, Sparkfun has supplied a example code! I am already getting this for light painting.
45  Using Arduino / Project Guidance / 56k IR Reciever with Red/Yellow/Green Indicator on: July 13, 2011, 07:46:37 pm
Yesterday I bought this board from the scrap bin at All Electronics: http://www.flickr.com/photos/chrisjelledge/

What I know about this board is that it has a IR receiver with the following specs:



  _________  Infrared sensor module
  |     _      |  Numbers printed on the top:
  |   |  |    |  TK69   931
  |   |  |    |  TSOP  1738
  |   |  |    |
  |   |  |    |  Front view showing the area
  |__|_|__|  receiving the IR signal
   |   |       |
   |   |       |
   |   |       |
   |   |       |
   |   |       |
   |   |       |
Gnd  |      Output
      +5V

There is a 12 pin right angle pin header on the board.

Is there any way I can use this to make a IR Power switch?
