I need to build an electronic voting system to collect audience opinions (maybe using a radio frequency device) and pass the result to a pc for processing. Users should have a device with different buttons (2 or 9) and they should be queried by a master system on reception of PC command.
Does anyone have any reference for a project like this?
I had one from an italian magazine but they don't have the PIC software anymore so it's not use.
thanks in advance
