When producing Muttering, we use Arduino IDE to configure two Touch Board boards as unique vocalizers with conversational capabilities. The Touch Board utilizes MPR121 capacitive touch sensors to detect touches and foot steps on the electrodes of the touchpad, thus identifying user interaction. Muttering interprets these signals from the capacitive touch sensors, converts them into MIDI signals, outputs them to an audio amplifier to drive corresponding sounds from the speaker unit, while also controlling device lighting to generate variations. Additionally, another Touch Board board receives signals to provide corresponding responses, achieving a performance where the device and the user collectively present a combination of bodily movements with visual and auditory elements.
