Beginner want to know arduino

Projects General Guidance
1

I would like to know what kind of arduino that most suitable with PIR motion sensor. I would like to build my automatic lamp switch as my project.

thank you.. :slight_smile:

Uno.

If you just want a motion sensing lamp then an arduino is incredibly overkill you could do the same thing with discrete logic chips or just a few transistors.

I think all you would need is a NOT gate(depending on how your motion sensor works) and a relay.

Yeah, but where's the fun in that? No programming, no different modes of operation, no expandability, no means to bring in Real Time Clock for alarm clock programmability, or an RF module for remote control ...

Thanks for your both advice..
Is it uno R3? what is the different with the old one?

Overkill is an often underrated achievement.

An Uno R3 will be fine. Really, any arduino with a USB connection would work easily for this project.

R3 and other previous model are basically the same. You can even get yourself a clone (which is cheaper) if you want.

If I'd like to combine 2 projects in one arduino (theft alarm & automatic lamp switch). Different actuator.
Is it possible using Uno R3 or not?

thanks. :slight_smile: :slight_smile:

I don't see why you can't. It does complicate the programming, in that you have to calculate the minimum delay for either side and then check which event to do.
