Setting up a headless Raspberry Pi doesn’t have to involve hunting for its IP address. With mDNS (Multicast DNS) and a proper preconfiguration in Raspberry Pi Imager, you can SSH into your Pi using its hostname (e.g., rootsaid.local)—no screen, keyboard, or router login required. This guide walks you through the exact steps and explains how…

Overview AI and Arduino are combined to create a quiz-to-unlock smart lock. OpenAI generates a short question and validates the reply; the Arduino Nano ESP32 controls a 12 V solenoid via MOSFET/relay and updates an Arduino IoT Cloud dashboard. Correct answer → brief unlock. Wrong answer → buzzer pattern and reset. Hardware remains minimal; intelligence…
