 ## Introduction & The Point
 
-The Octopus Flex PCB (SulaJamlari) is a desk toy intended to provide a hands-on learning experience with embedded systems, IoT technologies, and PCB design.

-People often ask what the "point" of this project is, but there isn't a strictly functional one. It was created to see what happens when art meets engineering, to learn device development, and to be a challenge. The point was the journey—and, of course, because an octopus desk toy looks incredibly cool.

 ### The Fun Things
 * **Wobble Physics:** Because the assembled PCBs take the physical shape of an octopus, the whole device wobbles when shaken.
-* **Visible PWM:** When the device is wobbling and the LEDs are running PWM, the movement actually allows you to see the PWM strobing with your naked eye.
+* **Visible PWM:** When the device is wobbling and the LEDs are running PWM, the movement actually allows you to see the PWM cycle with your naked eye.
 * **Tap-to-Click:** The IMU is mounted in the very top of the head. This means you can tap the top of the device, and the accelerometer registers it as a physical button press.
 
 ### The Flaws (Lessons Learned)
 * **Durability Limits:** During "stress testing" (read: repeatedly slamming it against the base board), some of the MCU pins eventually detached. Please don't torture the electronics!
 * **Haptics:** The vibration motor was mostly unnoticeable, leading to its removal from the final assembly. (Pins to connect a motor still exist)
-* **Logistics:** Transporting an assembled, multi-layered flex-PCB octopus safely is tricky.

 ### Zephyr Framework
 Initially, Zephyr felt overwhelming due to deprecated documentation and a steep learning curve with devicetrees. However, to get the Bluetooth functionality we wanted, we gave it another shot. Eventually ended up enjoying having "one framework to rule them all", plus gaining embedded Linux/devicetree experience was highly valuable. The custom board files use the `nrf52840-dk` as a template. Zephyr relies on **MCUboot** as its bootloader.
 
-### Arduino Support
-For broader accessibility, the Adafruit nRF52 library and bootloader was modified to work with the Octopus Flex PCB in the Arduino IDE.
