Roboduino on Instagram: "🔒I build a touch sensor password lock using Arduino UNO and a servo motor ⚙️. This project is inspired by real-life security systems such as bank lockers, gym lockers, office cabinets, and personal storage, where access is only granted when the correct password is entered. Instead of using traditional keys or push buttons, I use touch sensors to create a password sequence. Arduino checks the sequence, and when it matches, the servo motor unlocks the system. If the passw
