Kinetic Pterodactyl: Light, Motion & Code. Advanced

Description

Kinetic Pterodactyl is a hands-on educational robotics project designed for a creative STEM camp, where pupils build, program, and take home a fully working kinetic sculpture. Inspired by classic bird flapping mechanisms, the project replaces the bird with a dynamic pterodactyl whose wings flap realistically using a gear-based mechanical system.

At the heart of the model is a DC motor driven through a DRV8833 motor driver, controlled by a LoLin (ESP-based) board. Students assemble the mechanical transmission themselves --gears, shafts, and linkages, learning how rotational motion is converted into rhythmic wing flapping. Beneath the pterodactyl, an LED strip provides expressive under-lighting, transforming the model into a glowing kinetic display.

Beyond mechanics, pupils program the system to control motor behavior and design custom LED color patterns. They experiment with speed, direction, timing, and light animations, gaining practical experience in embedded programming and creative problem-solving. The project blends engineering, coding, and art into a single engaging build -- and at the end of the camp, every pupil proudly takes their animated pterodactyl home.

That is take home project!
