🧠 What is ARDU-8051?

ARDU-8051 is a complete open-source learning platform designed to teach the 8051 microcontroller in a modern, practical, and globally accessible way.

It combines:

• ✔ Open-source hardware
• ✔ Assembly-level programming
• ✔ Browser-based virtual lab
• ✔ Real hardware ↔ simulator parity
• ✔ Arduino-compatible form factor

Suitable for:

• Engineering universities & colleges
• Remote and blended learning
• Self-learners and hobbyists
• Teachers and lab instructors

🎯 Educational Motivation

The 8051 microcontroller is still widely taught, but teaching tools are outdated.

Common problems:

• Obsolete trainer boards
• No reliable simulators
• Proprietary programmers
• Weak connection between theory and practice

ARDU-8051 solves this by:

• Integrating hardware and simulation
• Using industry-style workflows
• Remaining fully open-source
• Supporting learning anywhere, anytime
