Access Control Device
Built an advanced hardware-based access control system using RP2040 microcontrollers and RFID technology.
Project Overview
This hardware project involved designing a secure entry system controlled by a laptop interfaced with multiple microcontrollers. I utilized an RP2040 (Raspberry Pi Silicon) to coordinate high-speed communication between various peripherals.
The system features an RFID reader for credential verification, which triggers a high-security solenoid lock mechanism upon successful authentication. I also implemented a diagnostic feedback system with LEDs flashing at one-second intervals to indicate active system status.
Technologies Used: RP2040, C++, RFID, Solenoid Actuators, IoT.
Key Learnings: Hardware-software interfacing, real-time diagnostic systems, microcontroller programming, and electronic circuit design.
Hardware Interface
The system is monitored and managed via a connected laptop, providing a real-time interface for access logging and administrative controls, interfaced with an RP2040 microcontroller.
