Teacher-student responder

[sassyboy]

Dear all

I am a maths teacher and am keen to build 30 wireless responders over the summer holiday to allow my pupils to respond to my multiple choice or true/false questions via a wireless responder. The survey is then displayed on the computer screen.

I would be grateful if you could provide me with some ideas of circuit diagrams or articles that directly relate to my need. I thank you all in advance.
