We want to make an exhibit type game that has three stations, each station with three cut-outs to set something in. If the right piece is set in the cut-out a light flashes and a score on a screen is updated. I'm thinking rfid is best and in doing research, phidgets seems to come up as a respected brand, so here I am.
My preliminary research suggests that I will need a total of 9 rfid readers (3 cut-outs in 3 different stations) and then at least 9 passive rfid tags to be placed inside the individual pieces. Then I can write a program that compares the data sent, to the reader that sent it. If it's correct increment the score by 1 and send a signal (x10 maybe?) to illuminate the light.
I would love feedback on phidgets products that would make my goal easier to attain.
