The DIY Piano Module is a compact, beginner-friendly electronic sound generator designed to bring music and electronics together. Powered by the popular NE555 timer IC in astable mode, this module produces distinct musical tones by switching between resistor-capacitor (RC) networks linked to piano-style keys. Each key corresponds to a unique frequency, allowing users to play notes ranging from “Sa, Ri, Ga, Ma, Pa, Da, Ni, Sa (higher octave).”
With its simple hardware design, no programming requirements, and easy-to-assemble layout, the Piano Module is perfect for classrooms, hobby projects, and DIY musical experiments. Whether you’re teaching oscillators, building a fun electronic toy, or exploring sound generation, this module offers an engaging hands-on experience.
Key Features:
- Simple Design – Built around the NE555 timer IC with minimal external components.
