You also learned more about how to interface with OLED screens over both SPI and I2C and how to connect everything in a small form factor. This chapter also introduced you to some leather crafting and how to shape your project into a watch.

While we have created a working Wi-Fi connected watch with some notifications from different online services, we have barely scratched the surface of the possibilities for your smart watch. Hopefully, you have gained enough insight to start developing the project in the future in order to meet your needs and wishes.
