Prototype, prototype, prototype

One thing we got reiterated on the Plantarduino project, is that in order to be sure that something is going to work, it is necessary to build a mock up.

Sometimes one mockup will prove sufficient, often it is necessary to build a couple. We built quite a few because we were opening a water valve with a servo we needed the alignment to be good always. The prototype also allowed us to see where we needed mounting holes for all the components.
