Can't get multiple servos to work simultaneously using servo easing library
Hi, all. titles not a 100% accurate. i was able to take the threeServos code example off the library's github(https://github.com/ArminJo/ServoEasing/blob/master/examples/ThreeServos/ThreeServos.ino) and butcher it to my purposes. but now i'm not able to change the motor speed, no matter what number i use for the setSpeedForAllServos() function the motors always move at the same speed. but frankly i dont even understand how the code i have here works.

It’s getting there! Comment with more details
I have a robot that looks similar to yours and I can stop an issue with your current software. The reason your entire arm is flexing when the servo stops is of course realated the weak first link between the upper part oft the arm and the socket. But an easy way to fix it (get around it) is by utilizing easing. When the servo should go from 0 to 90 degrees, make it go really slowy from 0 to 20 maybe and then reallt fast from 70 to 90 make it go slowly again. Of course you can use cubic easing to get a velocity near zero before the servo stops. A great library that you can use us ServoEasing. https://www.arduino.cc/reference/en/libraries/servoeasing/ GitHub: https://github.com/ArminJo/ServoEasing

Arduino Uno Bootloader flash Issues
I used MiniCore with some help from this ARTICLE and was able to flash my uno but encountered some more problems

definitive guide on programming the SMD ATmega328 or ATmega32u4?
Once you buy the programmer, install the drivers on your computer. Your Arduino IDE will also need the correct "boards" installed to program all the different microcontrollers. This is done through the "Boards Manager." Use the MiniCore GitHub page to install the Atmega328.
- Having trouble communicating with a CP2102 IC on a custom board. Simplicity Studio says it is not recognised properly even though it does show up. Tried replacing drivers with Zadig, no change. Perhaps the schematic is wrong?

ATMEGA328PB-MU TWI Issue
To be on the safe side you may want to install a 3rd party "Arduino core" specific for this chip, in case some pinouts or constants were changed compared to to earlier ATmega328 chips. Google gave me this: https://github.com/MCUdude/MiniCore ; others may exist.

Burning a bootloader onto an ATmega328p.
If you do want to use the Arduino libraries and Arduino IDE as normal you need to install MCDude's MiniCore which is an implementation of Arduino that lets you work directly with the chips (i.e. the "board" in the Arduino IDE is the chip directly). In the link above you can find amongst others install instructions and the maps of the chip pins to Arduino pins (which you need to know which microcontroller pin corresponds to which Arduino pin number when you do things like digitalWrite).

Running ATMEGA328P at 27mhz?
You'd need to create your own board definition as the default install only handles 16MHz. MCUdude's MiniCore core shows how this could be done: https://github.com/MCUdude/MiniCore
