Step 3: Electronics Pt. 3: LED Lighting

LED lights are cheap and easy to use - and if used in the right way, can add to the asthetics of a project tremendously.

I would reccomend going to eBay and buying an LED assortment. Whenever you need a color, you'll have it on hand. I purchased 7 colors of LEDs, 15 LEDs for each color, for about 6 dollars shipped.

If you want to drive more than one LED on the Arduino, you will need to use a transistor (basic schematic shown in pictures).

The LEDs are connected to the digital ports on the Roboduino, and used the digitalWrite command to turn the LEDs on and off.
<p>sir have you any video of this project for more clarification . i am very interested to to this project . email me the link at jyotiprakash210496@gmail.com</p>
<p>Can you show a video of the results?</p>
<p>Sure, here are the Vimeo video links:</p><p>Here is a sample video of the turret:</p><p><a href="http://vimeo.com/3914462" rel="nofollow">http://vimeo.com/3914462</a><br>Here is the completed turret:<br><a href="http://vimeo.com/4070435" rel="nofollow">http://vimeo.com/4070435</a></p>

RadioShack sells these recording modules: you hit record, do your sound, and when you hit play it plays the sound recorded.
why don't you use a cheap mp3 player that uses sd cards and wire it up to the arduino board? there are loads of tutorials from instructables
This is really neat. One question though:<br><br>Where did you get the Portal audio samples? Can you post a link or something? That would be helpful for us users who want to do something like this!<br><br>Thanks!
If you have the non-steam version of portal, you can go into the files installed on your computer and find all the audio samples.
its also on the steam version
You should now try to make it look&nbsp;and sound&nbsp;like&nbsp;one from the game and have the doors swing open when someone&nbsp;sets it off.
yeah, it should say &quot;Are you still there?&quot; and &quot;I see you&quot; It would really freak someone out.
Can u made a tutorial how to make it from the begin??
do you need sound i just want to make one that fires
Can you make the turret ado fier
Would it be possible to use webcam instead of stampy method? :D
portal win
Sorry, I did not see the code.
Sorry no schematic, though. I didn't use one... just kind of threw things together with the Roboduino. Nothing was complicated, just hooked up some servos, leds, transistors, etc. I guess the wave shield was the most confusing but it's all on the ladyada web site.
How about schematics and codes?
Brilliant work! Well done! This must be the first gun turret I've seen with real character, even if it is taken from Portal, so what, it works great. The Arduino is well coded to give it great character. I was somewhat disappointed though that it doesn't make the loud alert bleeping sound when knocked over, as they do in the game. In Portal it gets all confused and shoots for a short while too before making a shutting down sound - as far as I can remember. Would be great to add that - should be quick to change the wave files, nudge nudge ;-) One thing though, If I'd have programmed it, I would have cut down the random chatter, just not speaking so often to cut down on the annoyance factor. Other than these very little gripes, awesome job!
I am soooo building this! I luv portal!
I had a sorta wacky idea, why not use some of the portal turret code in this project, have it pan around with an infra red camera, ultrasonic sensors (or that range finder) then, when it sees a person it triggers the same movement and speech code as the game (with the same sound files)
Hmm I might try that some day. But for now this turret is done, spent too much time on it so now I'm bored of it.
I might try to make this(good work on your turret project)
