This project is my DIY take on the classic "Little Professor" educational toy. It’s a compact, handheld calculator-style device designed to help my kids (or myself 😆 ) practice times tables. The device features a 2-inch landscape screen that displays math problems, and a 4x4 keypad built using the Adafruit NeoTrellis, allowing users to input their answers and a Raspberry Pi Pico to handle the logic. Once an answer is submitted, the device provides immediate feedback—letting the user know if it’s correct or not. The case will be 3D printed, designed for portability, ease of use, and visual appeal, with a retro-inspired look that blends nostalgic educational toys with modern maker aesthetics. Ideal for learning, tinkering, or as a fun electronics project!
