password-manager

This is my first app. SecureVault is a custom-built password manager with a sleek GUI using customtkinter. It allows users to securely save, edit, and delete passwords for various websites. Passwords are encrypted using Fernet (from the cryptography library), and access is protected by a hashed master password (bcrypt). Key features: βœ… User-friendly modern UI with dark/light mode πŸ” Master password login for extra security πŸ”‘ AES-encrypted password storage (Fernet) 🧠 Password strength checker πŸ› οΈ Password generator with one-click copy πŸ’Ύ Data stored locally in a secure SQLite database 🧹 Easily edit or delete saved passwords Ideal for students, developers, or anyone wanting a simple but powerful offline password vault.

Today I kicked off my first major project for Hack Club’s Summer of Making β€” SpeedStrike, an Arduino-powered reaction time tester!
I spent the session designing the core features:

🧠 AI Mode with difficulty levels

πŸ‘₯ Two-player competitive mode

πŸ”Š Buzzer feedback

πŸ“Š Average of last 5 reaction times

I wrote ~220 lines of optimized Arduino code, set up a clean repo structure on GitHub, and added a beautiful landscape banner to represent the project. Also configured arduino-cli in Codespaces, fixed library errors, and committed the firmware!

πŸš€ Big goal: Make the gameplay feel fast, fair, and fun β€” with visual feedback on an LCD and multiple input buttons on a breadboard.
Next step: Add game state animations and web documentation. Onward!

Arduino LCD Memory Game

This is a memory game built using Arduino Mega, a 16x2 I2C LCD display, buttons, and a buzzer. It’s a Simon Says-style game that displays a sequence on the screen, which the player must repeat by pressing the right buttons
