This project was for ‘Creative Electronics’, a Beng Electronics Engineering 4th year module at the University of Mlaga, School of Telecommunications (
The project has been designed and assembled by Carlos Almagro, Diego Jimnez and Alejandro Santana, we have made a box music player controlled by a Arduino Mega (we have chosen it because Arduino Leonardo wasn’t powerful enough for the neopixel matrix), that shows through a 8x32 neopixel matrix the spectrum of music. The main idea is to sample the sound signal in 8 bars (one bar in order to represent each frecuency interval, until 20kHz).
The signal enters through a jack 3.5 port and goes to the arduino and the speakears, previous step of being amplified.”
