🚀 What it is

​

The RallyLED WiFi Android Controller is a mobile app that connects directly to your RallyBoard (LED scoreboard) using WiFi—no cables, no extra hardware.

It turns your phone pr android table into a wireless remote control + smart interface for managing games in real time.

🔗 How it works 

• The ESP32 inside your RallyBoard creates a WiFi network (or joins one)

• The Android app connects to that network

• The app sends commands over WiFi → ESP32

• ESP32 → sends LED protocol (Serial2) → LED panel

👉 In simple terms:

Phone → WiFi → ESP32 → LED screen
