ESP32 Smart Watch
In this we are going to use a what we have learned to create our own smart watch from scratch, using a combination of hardware and software components. Throughout this part of the project, you will be guided through the process of assembling the hardware components, setting up the software, and configuring the settings and features of your smart watch. By the end of this project, you will have a fully functional smart watch that you can wear and use on a daily basis.
