Hello,
Me and a partner are working on a project where we need to active leds with voice commands. The module that we are using is the Voice recognition v3 module (http://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=&products_id=2254).
We’ve connected the module with a arduino uno and captured some words with a microphone that looks like this (http://ecx.images-amazon.com/images/I/31emj5Hi5DL.jpg)
In our case we would like that people talk and that the module is capturing the sound(/words) from a distance of aprox 1-3 meters.
But the microphone only works if you say something from a distance of 5-20cm..
So we’ve tried to make our own microphone with this amplifier http://www.velleman.eu/images/products/0/k1803_np.jpg + http://vikash.info/audio/measurement_mic/images/wm-61a_capsules01.jpg
But that doesn’t give us any input of information when we look at the serial monitor when using arduino sketch..
Does someone has some tips for our project?
