Android mit inventor app with Arduino UNO and esp32

I have an Arduino based project with an esp32 as the main MCU working as the hub connected to two arduino uno via i2c . The esp32 is connected to an ili9341 tft, an sd card where the data is saved, and its own encoder. Each arduino uno has 1 rotary encoder with a button buttons, 1 PWM, and one switch. First encoder for the PWM has a frequency from 1 to 1000, The button of the encoder is to multiply the value by 10 or divide by 10 when pressed.. Each UNO is will ready 4 analog inputs to both . The values of the encoders and the eight analog channels will be displayed on both the android screen as well as the tft lcd . The esp32 will use Arduino code, while the host GUI will be an android app using [login to view URL] based on mit inventor app that controls each UNO PWM for duty and frequency. The app will record 100 points of each analog channel along the full range of the duty cycle (100 samples). Then the data will be saved locally to the filesystem of the esp32 as well as to a GitHub directory, which will serve as a backup. In addition to the encoders, the android app will also control the hardware. On the android screen, there will be two windows, and each window will showcase 4 graphs per each UNO The first window will display the first set of four channels of 1st UNO , with each graph of a specific frequency of the PWM1. The first graph will be the baseline of a specified frequency during the auto mode where x is the duty cycle and y is the value of each of the first set of four analog channels. The default for the auto mode is an increment of half of a second for each of the 100 points. However, this can be changed anywhere between 1 to 1000 milliseconds. Each subsequent graph will simply have another specified frequency. The second window will be the same except that it will display the second set of 4 channels of UNO #2 analogs and PWM2 frequency. All frequencies can be chosen via an input from a digital encoder widget on the Android screen or via the connected knob encoders on each UNO. All values will be displayed on both the android screen and the LCD ili9341 tft screen regardless of where they are switched, whether the android app or the manual moving of the knobs. Every data file will be downloaded from and/or uploaded to GitHub in text format. Finally, the android app will have the ability to display four files simultaneously for comparison and a URL link to the download of any new firmware updates to the esp32, whenever they become available on GitHub as well. Accepted term is single milestone full payment when job is done and accepted.

one milestone that is when delivering the project fully working.

this work is a bonus
i need this project done with modbus , esp32 to arduino uno i2c modbus also i need you to write me a extensions one for modbus and another one PID extension for mit inventor, nice ui and data analysis and graphing is vital to consider offers.
