FAQ
How do you test the firmware?
I do software simulation as well as test with real hardware to ensure the firmware is working and it is compatible.
I have a custom PCB, can you write the code for it?
Yes, If you already have the custom hardware ready for testing, oftentimes it is easier and faster way to check the firmware by running it on the actual hardware that the code is intended to be used.
I have a project idea and not sure where to start, what should I do?
Sometimes all you need is a great project idea to get started. If you are not entirely sure which microcontroller, sensors or modules to use. Well no need to worry because I will get that covered by selecting the suitable hardware and make a circuit diagram along with the code.
I need a web dashboard for my IOT project, can you help me with that?
A web dashboard is a great way to visualize data and control the hardware remotely and it is essential for any IOT project. So I can also design and develop a web interface for your project that you can run on any modern browser, if required.
Do you design a custom PCB for my project?
Making prototypes with readymade modules is the easiest way to test if the idea works but when you want to finalize the design you will require a custom PCB to mount everything on it. In that case I can also design a custom PCB for your project.
Why don't you provide unlimited revisions?
Revisions are necessary to ensure the work is done according to your plan. That's why I always share the results and working videos of the project before delivering the order to make sure the final delivery will be aligned with your order requirement.
I'm new to electronics, will you provide extensive support?
Yes of course. You can reach out to me anytime even after the order is finished if you face any difficulties and I will walk you through all the processes you need to do in order to complete the project at your convenience.
What gig package is suitable for my project?
Order budget depends on the complexity of the project. If you are unsure which one to choose then feel free to Contact me via messages or use Get a quote option and we can discuss the project and decide a budget and time for your custom requirement that suits both of us.
