RFID_Machine_Controller

This repository contains the hardware design files (eagle) and the firmware (Arduino) for the Fablab Winti RFID machine access controller.

Hardware features

  • Based on ESP8266 so it has direct access to WiFi
  • RFID reader
  • OLED display
  • Piezo buzzer
  • Multi-color LED
  • SD card for event logging
