The project consists of using an Arduino Uno to record and play audio in loop, using 1 button, a microphone and a speaker. Once the sound is recorded, the Arduino needs to automatically start playing this sound in loop. A momentary push-button is used to start recording the sound. As long as the push-button is pushed, audio is being recorded. Once the button is released, the audio needs to start...
