Glad you got it to work.
There is a mistake in the talking clock example on line #194
Code:
if (heure12) {
should be
Code:
if (heure>12) {

Thanks for the link to this!!!
I install it and it sounds great.  smiley-cool
You have to download the "Talkie-master.zip" file.
Un-zip it and open the "Talkie-Master folder"
When you get to the "Talkie" folder copy that folder and paste it in the Arduino library.
Open the IDE and it should compile correctly.
Thanks again!!!

The "Tom's Diner demo" is AMAZING!!!! smiley

Yes, but take a look at this for sound effects it's simpler and cheaper than midi. http://www.ebay.com/itm/Mini-SD-Card-MP3-Sound-Module-For-PIC-Arduino-WTV020-SD-16P-MM-/290839439562?pt=LH_DefaultDomain_0&hash=item43b761a8ca
Here's the thread about it http://forum.arduino.cc/index.php?topic=117009.0

Yes it can be done and with sound effects.
But most likely not powered from the Arduino board.
You will need additional hardware, components and a lot of time.
155  Using Arduino / Project Guidance / Re: Arduino Project to Activate Biogas Electricity Generator on Power Black Out on: September 13, 2013, 09:54:59 pm
Well the generator has nothing to do with switching from mains to the generator.
So that must be done through other hardware (Transfer Switch) attached to the mains usually right on the side of the mains box.
Give this a read: http://homemadecircuitsandschematics.blogspot.com/2013/05/grid-mains-to-generator-changeover.html
You could supply the starter with an Arduino and a relay. The problem is having the Arduino know when the generator has started so to stop spinning the starter.
If you can get the Arduino to sense that then your set.

Do you have the generator?
If so how do you like it? What's your source of bio gas?
I have a propane generator and really prefer it over my gas or diesel ones.
156  Using Arduino / Displays / Re: Touch screen sensitivity on: September 13, 2013, 03:09:46 pm
Is your outer screen tight against the LCD?
I had received one and it's outer screen had a slight raise to it.
If this is the case for you tell them and they should exchange it if the purchase was recent.

You need a debounce when the button is pressed.
Most easiest is
Code:
delay(your time here);
Better is following the blink without delay example.

This works well:

If using bare wires in the cloth like jack suggested, use stainless steel wire like for electric fences, so it don't corrode.

To help eliminate stealing you could have electromagnetic system tags incorporated into the tag to be scanned or inside the packaging under the tag.
Fruits and veggies could work if they were pre-packaged. Like carrots, potatoes, etc..
161  Using Arduino / General Electronics / Re: Amplifying the output of a ISD1820 on: September 04, 2013, 06:41:05 pm
Hey Dustin,
Glad you got it to work.

To have it be louder try building this LM386 based amp, and power it between 9v and 12v instead of 5v.
http://www.instructables.com/id/LM386-Audio-Amplifier/

Make sure you have a speaker that can handle the output of the amp.

The output of the ISD1820 is pretty decent on its own, the LM386 being powered at 5v really cant amplify the 3.3v or 5v signal from the ISD1820 much more.
Running the amp linked above at 9v or 12v will give you more amplification.
For even more power you could feed the 5v LM386 module you have into a larger amp, using the LM386 module as a pre-amp.
162  Using Arduino / General Electronics / Re: Amplifying the output of a ISD1820 on: September 02, 2013, 10:52:23 pm
Try this Dustin,
Flip the FT switch on the ISD1820 to the right. Turn the pot on the LM386 all the way to the left(towards the VCC pin on the LM386 module) speak through the mic and at the same time slightly turn the pot to the right until you hear your voice through the speaker.
163  Using Arduino / General Electronics / Re: Amplifying the output of a ISD1820 on: September 02, 2013, 10:43:08 pm
If your speaker works from the ISD1820 it should work from the LM386 amp.
My speaker is  2",  8ohm  and 1/2 watt.
164  Using Arduino / General Electronics / Re: Amplifying the output of a ISD1820 on: September 02, 2013, 10:29:50 pm
Works fine with my LM386 module.
Here's a pic of the connections:

Did you try the second circuit posted on the ISD1820 web page?
Are both circuits powered from the same source?
If not, are the grounds connected?
I tried it with a LM386 module and had to leave one of the outputs of the ISD1820 disconnected.
