An offline Android app for learning electronics and computer hardware.
ElectroBase is an offline Android reference app built for electronics and computer hardware students. It packs 80+ in-depth articles across 32 categories, 12 interactive calculators, a 147-term glossary, 10 circuit diagrams, a quiz engine, and a full note-taking system — all bundled locally with zero internet required.
This is the final project for the Android Development course at Palestine Technical College (PTCDB).
