This series of articles will run you by the design patterns the way it is explained in the Head First Design Patterns book using Go as the coding language.

Problem Statement 1:

• There is a WeatherData object which tracks current weather conditions (temperature, humidity and barometric pressure).
• Develop a Weather Monitoring Station that uses this object to provide three display elements : current conditions, weather statistics and a simple forecast, all updated in real time as in we acquire the most recent measurements.

Solution:

• 3 players in the system : the weather station (the physical device that acquires the actual weather data), the WeatherData object (that tracks the data coming from the Weather Station and updates the displays), and the display that shows users the current weather conditions.
