Ya, there’s always little things that one forgets with stuff like this. It normally will extend the completion date out at least a week or two further then expected. I just add that extra bit time into the project timetables now.
I made a PID with an arduino a few years ago just for shits and giggles. PID’s are really affordable though and outside of the ‘fun’ of doing it theirs no real benefit to it. But if you’d like to understand how PIDs work its a great project.
I’ve been using arduinos for some time now. I’ve built a fully automated air ride controller for a hotrod of mine before I could buy them or more accurately before I could afford them… Think accuair, ridetech, etc. Its still going strong after almost a 8 years now. I’m pretty proud of it really.
