I'm looking for some help in knowing what electronic parts I would need to purchase to create some wireless voting devices. Think of these as being used in a class room setting, where all 25 students would have a small wireless device that they could use to vote with. These devices would have, say, a 1-4 button choice. When I ask the students to vote for either 1, 2, 3 or 4, they would press the appropriate button on these small devices, and it would communicate with some kind of receiver (right?), that the software would then count up the choices. I'm fairly new at electronics, and I have found these types of machines for sale on the web, but I don't think I've found anything cheaper than about $1,000 for such a device? I would be using a laptop computer, I'm assuming, that probably already has a wirelesss receiver? I am a software engineer, so I'm hoping that any programming I would have to do would not be a big issue. Any direction would be greatly appreciated!
Thanks,
Craig
