Tune Player Using Arduino

Arduino board is designed for working with digital signal or square wave signal. If we want to generate sine wave, we have to do little effort, because analog output from arduino is not true analog but a PWM output which turn board on and off very frequently.

Here we use digital to analog converter to generate fine analog output. A digital to analog converter has a single output having number of digital input.
