Arduino Audio Output : 10 Steps (with Pictures ...
https://www.instructables.com/Arduino-Audio-Output/
DAC stands for "digital to analog converter." Since the Arduino does not have analog out capabilities, we need to use a DAC to convert digital data (numbers/ints/bytes) to an analog waveform (oscillating voltage). A simple, easy to program, and cheap way to do this is to use something called an R2R resistor ladder.
Using DAC's on an Arduino - XTronical

Below is the code shown in the video. Just copy and paste into the Arduino IDE. Sine Wave. // Create a sine wave on an oscilloscope using a 8 bit DAC // (C) XTronical 2019 // Use in any way you wish! // // As we're using an 8 bit value for the DAC 0-255 (256 parts) that means for us // there are 256 'bits' to a complete circle not 360 (as in ...

Playing Audio Sound Files ( Wav ) With an Arduino and a DAC: Play wav file Audio from your Audino SD card. This Instructable will show you how a wav file on your SdCard can be played through a simple circuit to a speaker.The wav file must be 8 bit mono. I have had no problem playing 44 KHz files.Whilst no…
Arduino Audio DAC Options - Use Arduino for Projects
https://duino4projects.com/arduino-audio-dac-options/
Arduino Audio DAC Options. DAC is short for Digital to Analog Converter. In this article we play around the code Michael Smith created for a PWM based DAC. I modified his code so that other DAC options could be tried. I compare the 8-Bit PWM DAC with the R2R DAC at various numbers of bits. You might be surprised at how well a 4-bit DAC sounds.

Thanks for all of the input guys. I think I am going to try to implement a simple DAC using an FGPA board, but I haven’t given up on the Arduino! I recently purchased the WAV shield for the Arduino that comes with a 10-bit DAC. For the Arduino project itself, I am going to try to make a basic audio player, much like an MP3 player with it.

DAC can be used in many applications such as Motor control, Control Brightness of the LED Lights, Audio Amplifier, Video Encoders, Data Acquisition Systems etc.. In many microcontrollers there is an internal DAC that can be used to produce analog output. But Arduino processors such as ATmega328/ATmega168 don’t have DAC inbuilt.
