At work, we have a system that lots of users interact with, but which sometimes needs some “alone time”. From time to time, we email our users and ask them to close the client application, so that it can do what it needs to do. (Needless to say, this software was not written in-house!) Users being what they are – and emails being what they are – this approach leaves something to be desired.
A colleague and I put our heads together and decided that we needed something obvious, intuitive and highly visible. “What if,” we thought, “we could wire up some traffic lights to a Raspberry Pi?” So that’s what we decided to do. In this multi-post blog series, I’ll outline what parts we used, how we wrote the software, and how we made our little old Pi ready for the enterprise environment. In this first episode, I’ll focus on how we got to a working proof-of-concept.
