With an iPhone 13, the easiest reliable way to connect to an “Arduino” project is Bluetooth Low Energy (BLE). iPhones do not support Bluetooth Classic serial (SPP), which is what many older Arduino Bluetooth modules use.
I need one more detail to give you exact steps:
  • Which board do you have? (e.g., Arduino Uno/Nano/Mega, Arduino Nano 33 BLE, Arduino MKR WiFi 1010, ESP32, etc.)
In the meantime, here are the correct options for iPhone 13:
  • If your board has BLE built in (Nano 33 BLE, some MKR boards): you can connect directly from an iOS app.
  • If you have an Uno/Nano/Mega (classic): add a BLE module (commonly HM-10–type BLE, or any BLE UART module) and connect to that. Avoid HC-05/HC-06 (Bluetooth Classic) for iPhone.
  • Wi‑Fi option: use a Wi‑Fi capable board (or add a Wi‑Fi module) and control it from Safari/app via a web page or HTTP/MQTT.
Tell me your Arduino model and what you want the phone to do (buttons? sensor readout?), and I’ll give you the exact wiring + code + iPhone app approach.

Looking for "Identify the Arduino/board model shown in the image (text on board, layout, connectors)." in eyJidWNrZXQiOiJncmF2aXRvbi1lbGVjdHJpYy1zeW1ib2xzIiwia2V5IjoicHJvamVjdC9jaGF0L2F0dGFjaG1lbnRzL2ltYWdlLTkwZTM5ZWFmLWQwYzgtNGIwYS05MDgxLTU4ZTYxYTQ5OTUwZS5qcGciLCJlZGl0cyI6eyJyZXNpemUiOnsid2lkdGgiOjE5MjAsImhlaWdodCI6MTkyMCwiZml0IjoiaW5zaWRlIiwiYmFja2dyb3VuZCI6eyJyIjowLCJnIjowLCJiIjowLCJhbHBoYSI6MH19fSwib3V0cHV0Rm9ybWF0IjoicG5nIn0=

Address.

I cant open that image link from here (it returns 404 Not Found), so I cant identify the board from it.
To help you connect it to your iPhone 13, please do one of these:
  • Re-upload the photo (or share a different link that opens in a normal browser), or
  • Tell me the exact text printed on the board (for example: "UNO", "NANO", "ESP32 DEVKIT", "MKR", etc.), or
  • Tell me what ports it has: USB-C / Micro-USB / barrel jack, and whether it has built-in Wi-Fi/Bluetooth.
While we wait: for iPhone 13, the usual rule is
  • BLE (Bluetooth Low Energy) works well.
  • Bluetooth Classic serial modules (like many "HC-05/HC-06" setups) generally wont work with iPhone apps for serial.
  • Wi-Fi is also a great option if your board supports it (or if it is an ESP32).
Tell me your board model (or re-upload the photo) and what you want the phone to do (send commands? view sensor data?), and I’ll give you the exact wiring + code + iPhone app steps.
