Über diesen Service
Turn your Arduino or ESP32 prototype requirements into structured firmware. I can help with sensor readings, control logic and device communication for a clearly defined hardware setup.
Before work starts, we agree on the board, components, pin connections and expected behavior. Delivery includes source code, a wiring or pin reference, and build instructions.
Packages cover increasing firmware scope, from one function to a connected prototype. Hardware testing is included only when the required components are available and agreed; otherwise the validation method and any client-side tests are documented in advance.
Components, shipping, PCB design, mobile apps and cloud dashboards are not included unless specifically quoted.
Message me with your board model, component list and desired behavior before ordering.
FAQ
Do you actually build the hardware, or just consult?
This gig is for consulting and design review. If you need full hardware development (PCB design, firmware writing from scratch, prototyping), let me know and I'll send you a custom offer.
Do you sign NDAs?
Yes. Send me yours before we discuss the project, or I can use a standard mutual NDA. Communication stays on Fiverr until both parties agree otherwise.
Do you send physical hardware?
No. This is a firmware service; physical prototyping is a separate scope.
Will you test on my exact board?
We confirm component availability before ordering and state the testing method in the offer.
Is a dashboard included?
No. A dashboard or mobile app is a separate deliverable.
