In this project, I use an Arduino UNO to record audio, that can be used for Speech Recognition purposes, with a MAX4466 Electret Microphone Amplifier. This is a fully assembled and tested board, that ...

Such a chip is the 386, not the 80386 microprocessor you were expecting but the LM386, a small 8-pin DIP audio amplifier that’s as old as the Ark. the ‘386 can still be found in places where a ...

[nickinoki] Made a light show using some amplifiers and an arduino. First he created a microphone circuit based around a LM386 Audio Amplifier. After amplifying the output of the microphone a secon… ...

There are several ESP32-A1S based Audio Boards: The AI-Thinker AudioKit is a popular example, the Espressif LyraT is another. The big advantage is that you don't need to bother about the wiring and ...

You can also use the on-board audio output jack to connect to your own amplifier/speaker set! This unit has a maximum recording time of 680 seconds, and a minimum recording time of 341 seconds.

Monitor amplifier for headphones; 4-pole LP filter for the on-chip DAC; Housing for Arduino Uno R4; The audio synthesis platform is structured on two PCBs: the Main board and the Display Board ...
