I am not 100% sure this question relevant here , but question is I have lv maxsonar ez which need 5v. I am powering my uno with 9v battery. And I have few other sensors also connected to 3.3v. But I have neopixel 3 meter LED which is powering with external power source which is 5v 4 amp. So My question is shall I connect my sonar sensor to the external power or keep with my uno 5v power ?

Thanks

If you've got a 4 amp supply, why are you bothering with a 9 V battery?

That's good question actually my arduino located way far from my led strip so that's why :( .. but I can make it wired with that.. but my question if I connect my sonar sensor 5v direct is it will burn my sensor out .. just in case ?
