DIY Smart Drawer Lock with ESP32-C3 + App Inventor (Password Protected!)

DIY Smart Drawer Lock with ESP32-C3 🔒
I built a smart drawer lock using an ESP32-C3, a servo motor, and an app created with MIT App Inventor.
The drawer can only be opened with a password 🔑 — a simple but powerful DIY electronics project!
