ESP-NOW RFID Display

Displays · Board: ESP8266 · Day 75 of 100

One ESP8266 scans RFID cards while another shows results on an OLED over ESP-NOW. Split sensing and display wirelessly.

How it works

The system splits in two: one ESP8266 scans RFID cards, the other drives an OLED. Scan results hop between them over ESP-NOW, so the display can sit far from the reader with no wires. Sensing and presentation, decoupled by radio.

What you'll learn

  • Split sensing/display architecture
  • Wireless display updates
  • Distributed UI design
  • ESP-NOW data forwarding
