Keypad access demo
Accepts a simple code and gives pass/fail feedback through light and sound.
Educational access-control prototype only. Not suitable for securing doors, valuables, vehicles, or buildings. Do not connect to mains locks or real security systems. RFID reader/cards are missing from the linked catalogue parts and must be sourced/tested before launch.
Mixed-board access-control draft for keypad/servo access logic while RFID catalogue parts are sourced and tested.
Proposed contents — confirmed in writing before you pay. Quantities and exact models may change if a part is unavailable, and we tell you before that happens.
Lost or damaged a part? Every part name below opens its own page, so you can buy a replacement or an extra on its own.
Every one is built from the parts in the box, plus the basics listed under You'll also need.
Accepts a simple code and gives pass/fail feedback through light and sound.
Moves a small model latch after an accepted input; not for real door security.
Compares 5V Arduino and 3.3V ESP32 wiring considerations before adding an RFID reader later.
