About this app

⚡ Learn Digital Electronics Visually – No More Boring Theory!

Digital Electronics Visual Lab transforms complex logic gates, flip-flops, counters, and Boolean algebra into an interactive, game-like experience. Whether you're a GATE aspirant, engineering student, or hobbyist, this app makes learning fast, fun, and effective.

🚀 What Makes This App Unique?

🎮 25+ Interactive Simulations
Tap switches, watch outputs change in real time. Experiment with:
• ALL basic gates (AND, OR, NOT, NAND, NOR, XOR, XNOR)
• Arithmetic circuits (Half/Full Adder, Half/Full Subtractor)
• Multiplexers, Demultiplexers, Decoders, Encoders
• Sequential circuits – D Latch, D/JK/T Flip-Flops
• 4-bit Ring Counter, Johnson Counter, SISO Shift Register

📚 120+ Bite‑Sized Concepts
Every topic follows our unique “3‑Step Learning”:
1. Real-life Analogy – understand intuitively
2. Visual Animation – see it work
3. Rule Summary – remember forever

Topics covered: Number Systems, Boolean Algebra, K‑Maps, Combinational & Sequential Circuits, Counters, Shift Registers, FSMs, Memory, ADC/DAC, Logic Families, and more.

🧠 Smart Practice with Step Hints
• 300+ practice questions with progressive hints
• “Mistake Learning” – see why your answer is wrong, not just the correct one
• Weak topic detection – focus on what you struggle with

🎯 350+ GATE Previous Year Questions
• Year-wise & topic-wise filters
• Built‑in timer
• Detailed explanations for every question

⚡ Quick Revision Mode
• Swipe through flashcards – 1 concept in 10 seconds
• Perfect before exams

🏆 Gamified Progress Tracking
• Earn XP for completed concepts
• Track accuracy and weak areas
• Daily quiz challenge (optional)

🎨 Modern UI / UX
