I found some cheap AI Thinker ESP32 Audio Kit V2.2 on AliExpress and because I was tired of all the wires I had to connect to implement my different scenarios that are possible with my Arduino Audio Tools Library, I thought it to be a good idea to buy this Read more…
Introduction I wanted to make some music streaming functionality available on Arduino. There are plenty of private music services using custom protocols which are out of reach. Fortunately there are also the open source protocols RTP and RTSP: RTP is the transport protocol for real-time data. It provides timestamp, sequence Read more…
Quite some time ago I have purchased an Audio Analog to Digital Converter (ADC) module, but I never managed to have it working properly. Unfortunately Google Search could not help either and I was the only one using this module or having problems. The Software Finally I have it working Read more…
I am trying to build an Arduino based Guitar Pedal with the help of a Microcontroller and some cheap standard modules. So far, I had the data input, the Audio Effects ready and just needed to put everything together. When I tried to demonstrate how to output the sound from Read more…
