Wireless button to talk to computer Answered
I'm running some sessions with a multi-abled theatre group of kids and we want to create a piece of interactive dance. Each kids will carry a couple of buttons and when they press them they send a signal wirelessly to a computer nearby which is running the dance program connected to a projector so the kids can see what they are doing. So pressing their button could change the colour of the kids projection from red to blue.
I think I need to use a microcontroller inside a button but am not sure which one - cheap and small - bluetooth or wifi? How do I get the button press program onto the microcontroller? Finally how does the computer hear the signal? The dance program is written in Processing.
Is there a project that is similar? I've searched for lots of things but can't find exactly what I need.
