More detail on the Talking Breathalyzer:




A customizable Breathalyzer that talks and tells you how much you’ve had to drink. It’s also open source and can easily be modified with your own text on the LCD screen and audio MP3 files.

When tethered to a PC with a USB cable, it has additional features including character animations, Breathalyzer Tweets, text to speech, weather and stock read-outs, and a Photobooth feature.

The Talking Breathalyzer is not a professional Breathalyzer and should be used for Amusement Purposes Only.

Step 1: Schematic and Assembly

Assemble following the schematic below. The assembly and layout will vary depending on the enclosure you are using. I used Adafruit's Arduino case but note that the Serial LCD used made by Seeedstudio is an older model, the new Serial LCD from Seeed will not fit into this case so you'll either need to find a bigger case or go with an alternative Serial LCD. I had a custom PCB board made but you can just as easily use a generic proto board and simply cut out the shape you need. This video describes the components of the Talking Breathalyzer.

great job man,but can you link where did you download voices

[alinke]

Hi, the voices were done by a professional voice actor, they are included in the software download from http://talkingbreathalyzer.com/software.html. After you run the install, you'll see them in "Your My Documents Director" \breathalyzer-files\Breathalyzer MP3s
