I was in PC world the other day and on exit noticed a white pedestal, with three big faces on buttons - it was obvious without any words that you needed to press a button to indicate your opinion of the service/satification of your trip. I teach and it would be great to have something similar near your door and students push the button on exit: Happy - Straight Face - Sad - Confused. I would then like to collate the data so that it is grouped by time (so I know the clicks between 9:00am and 10:00am are lesson 1 - and produce a bar graph on a self serving webpage for anyone to access.
I`m pretty sure this is all possible but I`ve not much of an idea of how to do it. I`m not a timewaster - I`m a do'er and this will happen if anyone is willing to help on the project, I`ll definately make it over the next few weeks and CHristmas holiday if anyone is willing to give me some tech support. I build clocks for a hobby but electronics is also in there www.raynerd.co.uk to see my projects.
Look forward to your replies!
First step is getting a pi to count button clicks which I could probably do. I have interacted with the GPIO before when I built the school Pi Weather station. I`ve no idea how the info would go in a database though and be processed or displayed.
Its a worth while project and I`m sure plenty of teachers would be interested if I could get one up a running.
