Ardunakon — Arduino Controller

Ardunakon is an Android controller app for Arduino projects. Connect over "Bluetooth Classic, Bluetooth LE (BLE), or Wi‑Fi (UDP)" and drive with a joystick plus dedicated servo controls.

- Highlights:
+Bluetooth Classic + BLE: Works with common modules (HC‑05/HC‑06, HM‑10/HC‑08, AT‑09, MLT‑BT05, Nordic UART, ArduinoBLE).
+ Wi‑Fi (UDP) mode: Device discovery and manual IP/port configuration.
+ Wi‑Fi encryption support: Handshake + AES‑GCM with a lock indicator when active.
+ Safety**: Emergency stop (E‑STOP) blocks control transmissions until reset.
+ Telemetry & debugging: Built-in debug console and real-time graphs (battery, RSSI, RTT, packet loss, quality).
+ Help built-in: Offline setup guide + compatibility report, plus an in-app tutorial.

- Compatible With:
+ Arduino UNO Q (BLE)
+ Arduino UNO R4 WiFi (BLE + Wi‑Fi sketches)
+ Classic Arduino boards with external Bluetooth modules (HC‑05/HC‑06, HM‑10‑style BLE modules)

Recent changes:
• New connections clear stale input and send a neutral control packet before live joystick commands.
• Arduino motor watchdogs are refreshed only by validated joystick packets, never by heartbeat traffic.
• Official motor sketches require a neutral packet after boot, timeout, or controller change before movement.
• Added ArdunakonSafeStarter with packet validation, neutral arming, E-stop, timeout disarming, and hardware fail-safe guidance.
