Microphone and Speaker Demo

I work with my friend, Joseph Trotta to make a device that insults you when you speak into the micro phone.

The wiring was very simple. We hooked up the microphone to an analog input pin, as well as power and ground. For the speaker, it is attached to a digital out pin, connected a resistor before reaching the ground.

By taking the input from the microphone, detecting a change in noise, we had the program say, "your breath stinks" to insult you. A very simple project but very interesting to work with sound with an arduino. I would love to play with sound more in the future.
