@funkyguy4000 The white board is an Arduino Mini Pro Artic Edition running at 16Mhz 5V.

@xl97 small world indeed.

Very cool blaster idea. Love the automatic firing option. Not applicable to V Visitor laser gun, but could be implemented for other ones. Will add that feature to my software. Implemented the INPUT_PULLUP pin method and combined it with the Ethernet shield.





Now I am activating the trigger over the Internet from my work and the laser gun is resting at my dinner table at home. Cool right?

Added for 1.0.1. Just tested and worked out like a charm. Right now testing an Ethernet shield r3. Connected it to the laser gun project and every time the server detects an incoming connection fires the laser gun. Very funny.

Sorry I did not get it from the very fist time. Reading that tutorial found out about the INPUTPULLUP mode, that saves you 1 line of code BTW.

Here you have the eBay link:

What attracted me from this amp was that is quite small and have two buttons to control the volume. AND could be controlled by Arduino.

Pretty decent. Played a few tracks from a PSB album I had converted and they were very cool and loud. I also bought an amp:



Still waiting to receive it. Keep you posted.

PS: Volume can be modified by software in this board.

as a matter of fact, that one is the second one I bought. Still waiting for a replacement. 2nd one is working on 3.3v. did not dare to turn to 5v yet until I get a replacement for the first one.  smiley-razz

Migrated to Arduino Mini Pro Artic Edition:





Will be optimizing the circuit as well the software. But have to report that audio module and library I wrote did work like a charm.

Wow! Thanks, good to know about that. Gracias Martin, yo tambien soy de Argentina.

PD: Encontre este ejemplo despues de investigar: http://www.arduino.cc/en/Tutorial/InputPullupSerial
71  Using Arduino / General Electronics / Re: Newbie question about Vcc on: August 15, 2012, 12:44:10 pm
Right. My problem is that I will be using an unregulated power supply to feed the arduino mini pro, so I don't have a 5v power source to feed the switch. So I was thinking in re-use an available pin to do that work.
72  Using Arduino / General Electronics / Re: Newbie question about Vcc on: August 15, 2012, 12:21:58 pm
I think I did not explained my self. Just take a look at this circuit:



I was talking about using a pin 7 in high state to feed the switch instead of connect the 5v.

Actually working on this:



and migrated the sketch to a Mini Pro this night. Wanted to know IF It is a good practice to use an available pin to feed signal for a pull up switch. Do you know what I mean? For example, I have pin 8 and 9 free, and would like to use one of them to supply trigger switch.

This one will work and only cost 6 dollars.

Finally did what I wanted to do from the very beginning with this audio module:
