Arduino standalone Audio generation - How to play Audio Signals from Arduino without modules using PCM signals

Timer 5:26 AM Arduino DIY MP3, Arduino Lonely Project, Arduino PCM, Arduino standalone Audio generation - How to play Audio Signals from Arduino without modules using PCM signals, Arduino Uno

In this post we'll see how to generate audio signals from Arduino without using any shields or modules.

PCM (Pulse Code Modulation)

Using Arduino and a speaker, you can generate audio signals as if they were coming out from an MP3 player.

Components

Arduino Uno

8 ohm Speaker

TIP 120 Resistor to be used as an amplifier.

Circuit

Just connect the amplifier transistor to Arduino and then connect them to the speaker.

Software
Download Audacity and then download software encoder from here.

Arduino code is included in this file.
