I've also been thinking about buying a 3D printer lately and this post has been a good help in comparing and choosing.

Great post, thanks a lot for sharing.

That's a great idea.

Does it only work for Arduino nano? I have an Arduino UNO board and I don't know if I can achieve the same function.

Thanks for sharing the code, it would be nice to have a video demo.

I think these look very interesting to do with small children may be able to stimulate their curiosity, the current video games are too much influence on children, occasionally the family together to do their own small games is a new experience.

This record is really detailed, thanks for sharing.

MySensors is a great framework and probably everyone has found other controllers and tools that work better or are more suitable for them.

Thank you very much for sharing, this is really helpful to me

Is it similar in nature to a temperature alarm?
