https://github.com/s-0-p-h-i-a/ICE_Engine_Simulation

An ECU firmware–inspired internal combustion engine simulation prototype.

This project aims to incrementally combine small engine sub-system simulations into a single control system. The goal is not realism or performance, but learning how engine-related components interact, how data flows through a system, and how to design, test, and refactor firmware modules.

Current capabilities

• Live RPM calculation using a Hall sensor and servo-driven “flywheel” with magnet for edge signal generation
• LED-based cylinder state visualisation (combustion cycle)
• Joystick-based runtime control (enable/disable modules, speed selection)
• Data interface feeding live telemetry to a plotter

Planned extensions

• Crankshaft module
• Cylinder head simulation (DOHC, valves, injectors, ignition)
• Communication with data logger MCU
• Fault injection and diagnostics experiments

https://github.com/s-0-p-h-i-a/Arduino_Practice/tree/main/Analog_IO%2BData_Logger

A firmware-inspired control and logging system with 2 microcontrollers connected via UART.

Project goal: build performance firmware-like control system while implementing error handling and logging, and laying foundations for future fault injection.

I/O MCU

• Takes user/sensor input via joystick, potentiometer and water sensor and processes input data to control the colour of an RGB LED via PWM
• Error handling system uses error codes to log sub-system states
• Produces periodic system snapshots with I/O data and error codes, and transmits them to data logger MCU via UART

Data Logger MCU

• Receives TX MCU system snapshots
• Processes received data and displays system reports on serial plotter and I/O data as LED matrix visualisation

Current Status

• High-level system design complete
• First code draft compiled
• Ongoing validation testing through progressive integration of different modules and functionalities

• Engine Modules
  https://github.com/s-0-p-h-i-a/Engine_Modules
  Isolated engine-related modules and experiments developed before integration into the main system.

• Arduino Practice Projects
  https://github.com/s-0-p-h-i-a/Arduino_Practice
  Small hardware and sensor projects focused on fundamentals.

• CLI C / C++ Practice
  https://github.com/s-0-p-h-i-a/CLI_Apps
  Console-based programs used to practice core language concepts and control flow.
