i am learning to use embrio and hook up sensors and have almost no experince with programming and hardware, this is a small project to learn a little more about this..

the experince i have is with ready to use engine managment systems and hook up sensors etc in an easy to understand software and tuning the engine with the program..




to the project i have set up a LED to pin 13 on an arduino uno and a NTC sensor to read temprature
i have used the raw signal i see in the program to activate the LED with "above or beow"
and it works great!

BUT i want to convert this raw value to a temprature reading that makes sense (celsius)
for starters in the embrio program and later out to an LCD for example

here is the sensor i`m reading

and i there are also the specs for it


i have set up the sensor like this

i have tried to search and find something abou this with no result

please help me, i love the concept of the program for my projects

You can either write your own node that takes an activation input and calculates the temperature and outputs it as a whole number. Info about making your own nodes is here: http://www.embrio.io/documentation/getting-started/creating-and-editing-nodes.

Or you can make a custom arduino node that does the reading and converting and outputs a number. tutorial here.

I suggest doing a custom arduino node, it's a bit easier and you should be able to mostly just cut and paste code from an example online.

Let me know if you have any problems!
