You will get Firmware (Arduino, ESP32) with sensors & display integration
Project details
I offer microcontroller (STM32F, NRF52, ESP32, Arduino, NodeMCU, PIC16F) firmware development with custom sensors, modules, and display integration. With extensive experience working on various displays (OLED, TFT, LCD), sensors (temperature, motion, gyroscopes, etc.), and modules (SD cards, communication interfaces), I ensure seamless and efficient solutions tailored to your project. Whether it's a simple single-sensor setup or a complex multi-module system, I provide reliable firmware and can also offer optional custom PCB design for a complete hardware solution.
