I built animatronic eyes with an Arduino UNO and a browser block-coding app for install-free programming

An automation control and robotics engineering student built a pair of animatronic eyes using two servos (left-right and up-down), a 3D-printed frame, and an Arduino UNO. He developed a web app offering Spanish Scratch-style block programming, a simulator to preview movements before connecting, and direct USB program upload through the browser (Chrome or Edge); each block also shows its corresponding C++ code and can be downloaded as an .ino file.
