Prototype Testing

Concept summary and connections

Our cardboard photogates are what's called a proof-of-concept prototype. Their only purpose is to prove that arranging our electronic parts as a gate will let us do what we're trying to do. But, once we've made the prototype are we done with it?

No! We actually have to test it.

Testing is an important part of the engineering process, in which you actually check to see if your design meets the requirements you identified earlier. Designing tests is a tricky business, because it's easy to miss the oddball things that happen in real life. The good news is that you can usually do more testing (unless you broke your stuff, which usually means you failed a test anyway...).
