ESP32 Dual-screen watch V2

Description

>Intro:
Just like with the previous project, this dual-screen watch was made with a multi-purpose role in mind, meaning that it can do more than tell time, it can also display the date, measure the steps you took, and many more. With the incentive of making the watch as compact as possible, I went on trying to reduce the amount of footprint inside, such as cutting down the circuit boards and using 28-AWG magnet wire to compress the circuitry inside. An additional challenge is that I don't need to sacrifice other functionality whilst reducing the size - maybe a testament to seeing how well I can fit that many components inside.
Of course, the feature that will not be sacrificed at all is the dual-screen functionality, That is the whole point of the watch, and having it cut out is not acceptable in my eyes. As a result, I'm left with a watch that is comparable to the other utility watches, such as ones made by CASIO, oh, and did I also mention that it's programmable?

Details

Just like from the previous watch, here's what it can do:

> Has an appealing GUI to make navigating with 6 buttons easily, and to save the OLEDs from burnout and increase the battery lifespan, it can go into light sleep automatically for a certain amount of seconds (only in GUI and time function). What made it different is that it truly used the dual-screen nature, allowing you to select options quickly

> GPS function (shows you your coordinates, speed and altitude, the GPS time and date, and measuring the distance from point A to point B, as well as cardinal directions.)

> Main time/date function, along with the ability to sync up time with the GPS and or External RTC(coming soon) to the Esp32's internal RTC.

> Health functionality: Heartrate detection (uses an external sensor, see the pic of how it's used), and a pedometer for calculating the steps you took.

> Games: can play Tetris and pong for added entertainment.

> Utility function: Has a stopwatch that also has a way to keep laps of time as well as an adjustable countdown timer.

> Misc functions: A visual on seeing how the mpu6050 operates, and the temperature function that uses the small dht11 sensor.

> Networking: has a wifi scanning functionality (though you will need to restart it every time you're done)

> Settings: You can adjust the CPU clock cycle, adjust the sleep time, enable/disable wifi, and/or even turn off the second OLED to make the watch run smoothly!
