Overview
One of 10 educational circuit boards we designed for a private training institution. The board takes an audio input from a phone or music player; the louder the music, the more LEDs light up on the board's 10-LED bar. It works just like the level meters on old stereo systems, showing students how sound can be turned into something visible.
Purpose and Goals
Our customer's goal was to show students how sound can be turned into light through a fun, visual example. We handled the full schematic and PCB design ourselves.
Development Process
After the needs analysis, we designed the circuit to light up LEDs based on the audio input. We delivered the schematic and PCB design to the training institution.
