D'oh! Didn't know the IDE had that feature. Very very handy. Oh well, it still passed the time at the airport, and was good practice for me doing guis in wxPython from scratch.

But no I'm not giong to add interactions with the computer from this, gobetwino already exists for people who don't program, and for people who do its way easier to just script something in Python or whatever.

I suppose I could add support for Arduinos to another program I wrote called Control Freak, which lets you control a bunch of things on the computer from a variety of sources, and Arduinos would be easy enough to add.

By the way if anyone needs some code to interface an Arduino with Python, I'm sure there's lots of examples around, but here's the code that's the core of ArduinoSpy:

I made a little program to interface an Arduino to Windows and soon Mac and Linux:

I needed something to get traces from my Arduino programs and had a long airport layover... Note that Gobetwino will show output from an Arduino too, but for me ArduinoSpy is a bit simpler for just getting debug messages. And plus variety is a good thing. Some notes:

- written in Python so once I get the kinks out I'll release it for Linux and Mac along with sourcecode

- minimal interface, and resizable and remembers window size & position.

- single file, no installer or registry involvement. Sorry about the file size (8 megs), the program itself is tiny but I have to include all the Python libraries.

- global hotkey: printscreen or scrolllock will connect/disconnect from the arduino. So if you need to upload a new version of your script to the arduino, hit printscreen to disconnect without having to focus on arduinospy.

- can automatically detect your arduino

- if you need to go to device manager to look up your arduino's comport number, view --> show device manager

- button turns green when connected, red when not, so you can see at a glance whether you're connected to an arduino.

This is most definitely a beta, and I haven't tested on the dreaded Vista. Feel free to let me know how it works or doesn't work for you or if you need it to do something it currently can't.

wrybread at gmail dot you know what.

Wow that would be fantastic if those were 12v. In the past I've owned an LED crosswalk sign, and if I remember correctly it was wired for 48v, which is brutal to work with for me.

Does your have any brand markings on it?

And did you have to physically open the sealed light fixture?

Would there be a way to dim these guys?

I'm guessing this would be much too slow:

I'm trying to hack an old traffic light, making the 3 incandescent AC bulbs independently controllable and, ideally, dimmable. My thought is to either have a series of buttons or a multi position switch to put the lights into different modes.

Modes could be:

- regular traffic light operation (green for awhile, then momentary yellow, then red for awhile, etc)
- dimmable sequence (red on then dim to yellow then dim to green, etc)
- dimmable random
- all on
- maybe somewhere down the road make them react to sound

This would all be pretty trivial if it weren't for the dimming part...

I found this discussion:

Which links to this kit:

But at $32 per kit, and the fact that I'd need 3, and the fact that I'd have to assemble each kit, I'm leery...

I also found this discussion:

Which links to this board:

But can't tell if that does what I need it to do.

I should probably add that I'm new to Arduinos but not to programming. I've been wanting to do an Arduino project forever, and this seems to fit the bill nicely.

Thanks gigantically for any help, and I'll keep this thread updated with source code and schematics as/if the project takes shape.

Very cool. I know this isn't exactly the purpose of a BlinkM, but is there a way to mod one so it can drive a relay? I'm guessing the LEDs are getting something in the range of 3.3 volts? Not the ideal voltage for a relay I know...

Thanks for all the sharing of knowledge. I ordered a BlinkM just because it looks like such an irresistably cool gizmo (if anyone wants a link, it's here, but have a feeling that I should bite the bullet and learn enough about Arduinos to use them to interface with a PC/Python to monitor inputs and control outputs.

I gather that I can set up a multiplex to have lots of inputs on just a few pins. Hopefully same with outputs.

Very interesting suggestions. I don't mind spending a couple of bucks. The lights will be up to 20 feet apart, so proximity isn't an issue.

I'd also like to be able to drive relays for regular incandescent lights.... Is that possible with these boards?

I need to control up to 50 LEDs from a computer, and possibly tri-color LEDs, meaning about 150 different pins to control. I really have no clue where to start, so thought I might post here to see if anyone has any ideas.

Using an Arduino as an intermediary between the LEDs and computer would be fine.

I'm programming savvy, and hope to eventually use Python as the controller language.

Anyone have any thoughts?

I'm trying to do something very similar: read the status of 20 buttons. Please post what you learn, and I'll do the same.

Argh, I didn't realize that circuit isn't able to transmit any frequency.

Do you know of any circuits that would let me do this? I essentially want to make this a universal remote. I'm guessing *someone* must have built an arduino-based universal remote before?

For my specific purposes, I need to send 15 different frequencies, all from the same gizmo.
42  Forum 2005-2010 (read only) / Interfacing / Question about sending IR codes on: October 11, 2007, 01:16:35 pm
I'm trying to get an Arduino to send IR codes to control a stereo. I found this project:

I plan to send different series of IR codes (like a macro) in response to different button presses on the buttons I'll be connecting to the Arduino.

Are there any other circuits I should consider? Anything else I should consider?

Thanks for any help.
43  Forum 2005-2010 (read only) / Interfacing / Amp meter for the Arduino? on: July 09, 2007, 03:35:36 pm
I'd like to be able to sense electrical current (if it matters, DC, in the 0 - 4 amp range) with the Arduino. I'm new the wonderful world of Arduinos, can anyone point me in the right direction?

And is there some main list of available sensors, etc?

Any tips at all?

Thanks for the help.
