Let's adopt this as our goal:

• We want to build programs in LabVIEW that take temperature data and store the data in a file.

• First, we need to learn about LabVIEW
• How to start the program, etc.
• Next, we need to know how to time things.  That may not be obvious, but we will probably need to know how to take data at user-specified time intervals.
• That is going to mean that we need to learn about loops and how to time them.
• We will need to learn about files.
• Opening, closing, writing data to the file.
• To write data to a file means that we need to learn about data formats.
• We will need to learn about floating point variables, integers, strings and what makes them all different.
• We will need to learn about converting between different kinds of data formats.
• We will need to learn about when we need to use different kinds of formats, and that rationale for that.
• And, we will examine how data format affects file size.
• We will need to learn about communicating with instruments.  That will include the data formats used by instruments and the typical kinds of commands that can be sent to the instruments.  Behind all of this is a bus structure that is commonly used in instruments, and we will need to learn about communicating with instruments.
• Eventually, if we want to view temperature remotely we will need an introduction to network communication using LabVIEW.
