I have 20 raspberries and I would like to do different task with my Y5-Y6 here are some of them:
Remote cars would be great but I haven't found WIFI based so we can use more than 5 cars in the same time
I also thought to build a server farm based on functionality (file server, game server, login server, webserver, email server) so children will be able to see what is 'the cloud' it should work but only as a test environment
using GPIO's with LEDs and sensors so we can collect weather data all around the school and see it somewhere...
visitors registering with small printer lunch
menu voting system/happiness voting system:)
What is the best network solution for these in a typical school? many thanks in advance
