Hi, I'm Aaron Trujillo 👋

Electrical Engineering Graduate | Hardware Test | Embedded Systems | Python Test Automation

I'm an Electrical Engineering graduate from California State University, Fullerton, focused on hardware validation, embedded systems, sensor testing, Python automation, and technical documentation.

My GitHub portfolio is built around one practical engineering workflow:

Design → Simulate → Test → Log Data → Analyze → Report

🔧 Core Engineering Skills

  • Hardware test and validation
  • Embedded systems and sensor interfaces
  • Arduino / Tiva-C / ARM Cortex-M
  • Python automation for data analysis and engineering reports
  • LTspice circuit simulation
  • KiCad PCB design
  • ADC logging and sensor classification
  • CSV data logging, plotting, and report generation
  • Technical documentation for engineering projects

## 🚀 Featured Engineering Projects

Project 4B — NTC Thermistor Temperature Test Bench

Wokwi Arduino Uno simulation using an NTC thermistor, ADC conversion, resistance calculation, Beta-equation temperature estimation, Python analysis, plots, and automated PDF reporting.

Engineering Focus: Sensor validation, ADC conversion, temperature classification, automated reporting Tools: Arduino, Wokwi, Python, matplotlib, CSV logging, PDF generation

Project 4A — Simulated Hardware Test Bench

Arduino potentiometer test bench that logs ADC voltage data, classifies readings as NORMAL / WARN / FAIL, and generates engineering plots and reports.

Engineering Focus: Hardware test workflow, signal classification, validation reporting Tools: Arduino, Wokwi, Python, CSV logging, matplotlib, PDF generation

Project 3 — Virtual Embedded Sensor Data Logger

Python-based embedded sensor simulation that generates ADC readings, logs data, creates plots, and produces automated engineering reports.

Engineering Focus: Embedded-style data logging, test automation, report generation Tools: Python, pandas, matplotlib, CSV files, PDF reporting

Project 1 — NTC Thermistor Voltage Divider

LTspice and KiCad-based thermistor voltage divider project with Python plotting and technical documentation.

Engineering Focus: Circuit simulation, thermistor modeling, voltage-divider analysis Tools: LTspice, KiCad, Python, circuit analysis, technical documentation
