Sunflower Light Tracker with ESP8266

This 3D-printed Sunflower Light Tracker is an interactive project built with an ESP8266 that combines electronics, automation, and 3D printing. The system uses a light sensor to detect the direction of the strongest light source and a stepper motor to move the sunflower accordingly, creating a fun and educational project for exploring electronics and IoT.
