Module development - using example of Temperature Nodes with 1-Wire PT100 / DS18B20 Sensor at multiple Locations

While developing a module, it is convenient in early stages to have all code in one and the same file, that is:

• module code
  
• some test code
  
• application (example) code
  
  

For a module example, I want to have a module that

• retrieves a temperature (polls)
  
  • from a given DS18B20 sensor
    
  • on given intervals
    
• holds on to the sensed temperature
  
• has a name for the temperature
  
• returns name and degrees in desired unit (Celsius or Fahrenheit)
  
  

This is good enough for now, because:

The focus of this conversation is less on the module and its functions but more so on the development process within the Espruino Eco System - IDE, Project, Sandbox, Module Compiler (js minifier), etc.

Subsequent post will walk you through the steps to build a module for yourself... and may be for others too.
