[3/30/2014] update: shield now for sale here
I just created a video showcasing the DTMF Shield for Arduino. The video is a simple demo of the features of the module and is to help promote the crowd-sourcing campaign that I have running in indiegogo.
Funny fact that half-way through the recording of the demo, I got a cold and lost my voice. So in order to finish the video on time, I had to use a very special personal assistant to help me with the narration. Check it out!!![youtube http://youtu.be/5YIfOYgompE]
