At the start I used a breadboard to get things working, but for a permanent fixture I have created a circuit board from strip board. (It was known as veroboard when I was younger). I have sockets for all the components so it's a lot easier if a component fails to just swap it out.
This is what the board looks like. The pink boxes are the sockets for the components.
In the next section we'll look at programming the various parts of the weather station.
