Electrical and Electronics Engineering student at Bülent Ecevit University working on ESP32 embedded firmware, circuit design, and hardware prototypes.
This site documents my hardware builds, schematics, and C/Python source code, including my ESP32-S3 2.4 GHz Multi-Functional RC Controller, ESP32 16-Track MIDI Breadboard Instrument, and 4WD RC / Autonomous Vehicle.
A handheld 2.4 GHz wireless transmitter and embedded control console powered by an ESP32-S3-N16R8 (16 MB Flash / 8 MB Octal PSRAM), nRF24L01+ PA+LNA RF transceiver, dual K-Silver Hall-effect gimbals, and shared SPI2 1.3" ST7789 IPS TFT + MicroSD bus.
A standalone dual-core ESP32 MIDI synthesizer, drum sequencer, and 30 FPS SPI OLED visualizer with a custom Python RLE MIDI-to-C compiler (midi_to_c.py), hardware PCNT rotary encoder, passive melody piezo, and dual active drum buzzers.
A companion 4WD robotic vehicle platform designed to pair with the 2.4 GHz Multi-Functional Controller while exploring closed-loop motor control, telemetry feedback, and autonomous obstacle-avoidance logic.
# 1. ESP32-S3 Multi-Functional Controller (ESP-IDF v5.2.2 + KiCad Schematic)
git clone https://git.ertuncozbay.dev/ertunc-ozbay/multi-functional-controller.git
cd multi-functional-controller/firmware && source ~/esp/esp-idf/export.sh && idf.py build
# 2. ESP32 16-Track MIDI Breadboard Synthesizer & Python RLE Compiler
git clone https://git.ertuncozbay.dev/ertunc-ozbay/midi-breadboard-instrument.git
cd midi-breadboard-instrument && python3 scripts/midi_to_c.py scripts/midillis/Alla_Turca/Alla_Turca.midFrom decoupling capacitors, BJT switches, and SPI bus arbitration up to FreeRTOS tasks and Python/Rust tooling—I study how every layer connects so I can take full ownership of what I build.
