In this, the last episode on making our own wav player we are going to look at how we can mix multiple sounds together. If you haven’t seen the previous articles in this series then this is highly recommened as they contain circuit digrams and show the other aspects of […]
In this article we add in volume control and go through the principles of changing the volume of digital samples. Video covering everything just below, source code/circuit even further below! If you’ve not seen the previous episodes then these are essential reading/watching. This was the last one – or use […]
A detailed look at how to play WAV’s from SD without using 3rd party libraries for transfer of WAV’s to I2S. It should give you enough detail to add this into your own code/wav players. Video Below which goes through everything and sources code/diagrams afterwards. INTROAs always time-codes are available […]
This is the first in a series of videos and articles explaining I2S and how to use with the ESP32. This opening episode keeps it very simple just using the included standard Espressiv libraries. In the video there is a full explanation of how I2S is implemented followed by a […]
We saw in the last instalment (here) how to simply play an MP3 on our ESP32. In this article/video we look at how to add volume control and to play all the MP3’s that we put on the root directory of our SD card (ignoring anything else). The video below […]
How to play MP3’s and other file formats on your ESP32 from an SD Card. All you need to know to make a simple music player. Code shown in video is below. Links:Github page for the library used : https://github.com/schreibfaul1/ESP32-audioI2S Affiliate links for the items shown: Clicking these costs you […]
This is a full tutorial for connecting up the PCM5102 or MAX98357A I2S decoder DAC’s. With the demo’s being how to use them for Internet Radio. It also includes a explanation of what I2S is and how it functions. I will build on this in future episodes which will show […]
This version fixes some bugs and adds an additional master volume option. Most of this work is courtesy of two subscribers. One of which did some significant bug fixes, especially on making the library work whilst writing to EEPROM. I only fixed one minor bug. But they don’t want any […]
This article shows how to use the MCP4725 DAC (Digital to Analogue Converter) on an Arduino. Arduino’s like many other MCU’s lack this useful functionality.
Driving a Speaker – Adding an Audio Amplifier (Adding the PAM8403 to a MCU) Piezo speakers (see here) are great where you don’t need high quality or loud sound or indeed where space is at a premium. But for anything else a small (or even large speaker) is the only […]
