To create a smartwatch using Arduino Uno R4 WiFi. This will provide features like step counting, location tracking, and temperature & humidity monitoring. Once all the data is collected, it will be sent to Arduino Cloud using WiFi or Thingspeak IoT. To show it to the user, it will be printed on a user interface which can be either an LCD or an OLED.

The application of developing such a device is vast because we can add more and more features like fall detection, vibration monitoring, beaconing tracking, and many more.

Once the basic framework of data acquisition is made and completed, more and more hardware & firmware features can be added to make it a user-facing product.
