DTMF Shield for Arduino SF_Robotics Kits Sensor is to create DigitalThis DTMF Shield is a Dual tone multi frequency signaling module decoder for Arduino With it's audio connector you can decode the crazy funny noises common phones make. If you are not sure what I'm talking about, imagine a home phone while pressing several of its keys. These Touch Tones have a specific frequency or sound that this module can decode. This Shield is an Audio code system that will allow you to send commands to your Arduino via Audio
