About this Gig
Hello Buyer
Need help building an embedded hardware prototype, programming an ESP32 or Arduino, or getting your IoT device to work reliably?
I develop embedded systems, ESP32 IoT solutions, Arduino firmware, and sensor-based prototypes that connect hardware and software. Whether you're starting with an idea, integrating sensors, or troubleshooting an existing project, I'll help you move toward a functional, well documented solution
Within My Expertise You'll Get
- ESP32 and Arduino programming
- Embedded firmware development and debugging
- Sensor integration and data acquisition
- IoT device development and wireless connectivity
- Microcontroller and peripheral interfacing
- GPIO, ADC, PWM, UART, SPI, and I2C integration
- Hardwarefirmware integration and troubleshooting
- Prototype improvements and functional testing
Technologies I Work with
- Microcontrollers: ESP32, ESP8266, Arduino, STM32, RP2040, AVR, PIC.
- Connectivity: Wi-Fi, Bluetooth/BLE, and supported wireless modules.
- Sensors: Temperature, humidity, ultrasonic, infrared, accelerometer, gyroscope, pressure, RFID, GPS/location, voltage, water, sound, and vibration.
- Interfaces: GPIO, ADC, PWM, UART, SPI, I²C.

FAQ
Can I request changes after the project has started?
within the agreed scope and revision limits. Changes that introduce new features, additional hardware, or substantial rework may require a revised price and delivery timeline.
How will I know whether the solution works as intended?
We'll agree on the expected behavior and appropriate verification steps before starting. Testing depends on the available hardware, simulation support, and the deliverables included in your order.
What if I'm unsure whether my project is technically feasible?
Describe the functions you want the device to perform and any limitations you already know about. I'll review the proposed scope and identify potential technical challenges before we proceed.
Can you help if my current prototype isn't working as expected?
Explain the symptoms, what you've already tried, and what results you expected. Existing code, circuit diagrams, error messages, and test results can help identify the next steps.
How do I know if my existing hardware is compatible with my project idea?
Compatibility depends on voltage levels, power requirements, communication interfaces, available pins, and component specifications. Share your hardware details so these factors can be reviewed before development begins.
What if I have an idea but don't know which components I need?
That's fine. Share your intended outcome and any reference materials you have. I'll help clarify the technical requirements and identify suitable components within the agreed project scope.
