Description
RFID, iButton MQTT Access Control
This ESP8266 sketch communicates with a Wiegand RFID reader and keypad. Ket features:
- Connect ot local MQTT server
- Send RFID codes over to MQTT
- Collect keypad presses and until # is pressed and send as a pin code over MQTT
- Block RFID readings and pin code entries too close to each other
- Neopixel LED provides visual feedback which is controller over MQTT
- Read ibutton keycards using a ibutton (one wire) reader
- Use A0 input as a digital input (e.g. state of the gate, garage door)
- 4 relay outputs to control gates, garage doors, lights, etc.
Please follow this project on my GitHub where you can find the Arduino sketch, Node-Red flow and also the BOM.
