Any help on implementing multiple sensors and readings on one Arduino would be appreciated.

I downloaded the Eagle free version, and watch all three videos. And i actually produce a usable circuit board.I found it's quite easy and quite straightforward and think that most people on this site will be able to actually produce a circuit board. The Software is quite intuitive and easy to use.

@Dalhoj I know it's not much of a help that I've been trying to do pretty much the same thing and using the same statements you are and countering the same problems, I'm not a programmer or from a programming background but I try and understand as much as possible about what's going on but I just can't seem to get my head around it..
Kind regards.

@ikjes said:

just one of the build
sensor node with smoke detection, mess light level, humidty and temp
en also the posibl to remotly test the smoke detector

and spare for motion detector and trip

Great idea, like the way you've doubled the function of the smoke detector by utilising the space.

@rvendrame thanks I think I get what you mean I'll give that a go still not sure if I'm On the right path.

Having a bit of problem receiving Data from another node am I missing something here or do I need to add something to the transmitting node. Just can't think where to go from here. HELP! Please.
Andy.

@FotoFieber Thank you for your response much appreciated I'm not much of a coder but I can feel my way through if I have examples to work from and this will help a bit .
Thank you Andy.

Is there someone who can tell me where I'm going wrong, here I can't seem to get the data from another node, Am I missing something here or do I have to put something in on my transmitting node, not sure where to go from here. HELP! Please.
Thanks Andy

Using through-hole & pants is fine for components i.e. NRF24l01. I found Eagle to have most of what I needed within the library but you can download more libraries by doing a search for Eagle libraries.

Is there a way of displaying radio information with in Vera, from each node i.e. signal strength and ID.

This is my first printed circuit, refined a little, might actually get this one done.

If you upload your design to https://oshpark.com they will quote you for free boards and it will give you a good representation of what you're bored will look like how cool is that.

@sansespere.. Nice work, I don't think I would've got most of that, now that should give me something to work from thanks.
