Project Description

I need an arduino device, that will be able to use a cheap cell phones keypad (transistors will be soldered to the phones keypad in order to simulate key presses). The device needs to reference 2 separate text files with data to know what to input through the keypad and create a third one as a log.

Here comes the hard part. The cell phones speaker leads will need to be used as either analog or digital inputs on the arduino itself or using a shield , in order to analyze sound. There will be 2 types of different sounds and the spectrum analyzer simply needs to tell which one of the two it is. No voice recognition necessary. Bid/message for further details.

(In a nutshell the device will replace a person who has to manually input data through a cellphone)
