Millis successful run sell my project from home ?

[74younus]

I want to make arduino projects and market them to sell or install in public domain. Can I do that.
I mean I want to manufacture at my home and then sell.

Probably.

But the rules, regulations, licensing and approvals you need to follow depend on where you are in the World.

And it could be a requirement of the software libraries you are using that you publich the source code into the public domain.

And dont forget to insure against your products causing harm.

And check that you're not running foul of the clauses in the datasheet for the processor that talk of use for life support and so on: check datasheet for the actual limitations.
