Remote button is a simple app and website bundled together to switch slides rapidly, and accurately with little human input to ensure success.
I made an app for the Assisstant Principal of my school (MENPS) called Remote Button. As the ICT captain I had to switch sides at assembly by hand which I found slow, inaccurate and annoying. So I made a program to automate this. Now the person using the application can switch slides with little to no delay, from the comfort of their seat.
