Inside the loop, we first set the output pin on the microcontroller to HIGH (1), then we wait for half the amount of calculated period & then set the output pin to LOW (0) and again wait for half the amount of calculated period. This way, we are operating at 50% duty cycle. Here is a simple output audio I created using the above method

2 Ways to Play Audio using a Microcontroller. By Ravi Pujar. Options #1. : Playing audio using an external audio/sound playback device. You can easily play audio in your project using an external sound recorder and playback device like APR9600/APR33A3 audio chipsets. These chips can record audio for a few seconds and play that audio when you press the play button.
The simplest way to play an audio file with a microcontroller?
