Arduino Basics

Project Description We will be using an MT8870 DTMF module with an Arduino UNO to control a small servo motor in this project. The DTMF module gives the Arduino super-powers and allows you to control the Servo motor in so many ways. For example, this tutorial will show you how to control the servo motor using: a YouTube Video a voice recorder A web application (Online tone generator) A smart phone app (DTMF Pad) A touch-tone phone to cell-phone call All of these control methods will take advantage of the same exact Arduino code/sketch. But how??? The MT8870 DTMF decoder is quite a neat little module that allows you incorporate DTMF technology into your arduino projects. DTMF stands for D ual- T one M ulti- F requency. DTMF tones are commonly associated with touch-tone phones and other telecommunication systems. When you press the number "1" on a touch-tone phone, two sine wav...
