Step-by-step Guide to Building AirTag using IndusBoard
Step 1: Setting Up the Hardware
Connect the 3.3V rechargeable battery to the IndusBoard Coin. Ensure the positive (red) and negative (black) terminals are properly aligned.
Attach the USB to UFL antenna cable to the UFL antenna connector on the IndusBoard Coin. This will enhance the WiFi range and accuracy of your AirTag.
Step 2: Configuring the Software
Open the Arduino IDE on your computer and load the provided code for the Enhanced AirTag project.
Configure the SSID and password for your phone’s hotspot in the code. This will allow you to access the device’s user interface (UI) for tracking purposes.
Implement data monitoring from the magnetometer accelerometer to capture movement, motion tracking, and direction information.
Create a web server page in the code to update real-time tracking data. Additionally, include a function to check WiFi connectivity with the device for seamless connection.
