Before sending a signal to speakers, you want to make sure it is oscillating around 0V (typical of audio signals). So far, the Arduino DAC output we've been dealing with is oscillating around 2.5V. To fix this we can use a big capacitor. As indicated in the schematic, I used a 220uF capacitor to DC offset my signal so that it oscillates around 0V.

analog output – you may find yourself needing to generate analog voltages from your Arduino at some point, maybe to communicate with an analog device effects box/digital signal processing – in combination with a microphone/audio input you can perform all kinds of digital signal manipulations and send the processed audio out to speakers.

The Arduino in the circuit shown below loads the .wav files from the micro-SD card. It then generates a signal and outputs it through the speaker connected to digital pin 9. This allows the speaker to create sounds and play music. In this tutorial, I have programmed the Arduino audio player to play "Rain Over Me” by Pitbull and Marc Anthony.

How Does the Arduino Speaker Work? The Arduino in this circuit creates tones of different frequencies and plays it through the speaker connected to it. The variation of the frequency of the tone (a.k.a. pitch) with correct timings (a.k.a. rhythm) creates music. The Arduino generates a signal and outputs it through the Digital pin 3.
