Mastermind Game IdeaJuly 26, 2012
When I was a kid we played a game called Mastermind. Basically one person makes up a code using colored plastic pegs and the other person tries to guess the code or pattern in a limited number of turns by placing colored pegs on the board and learning if any of his or her guesses are correct.
I thought to try and make an electronic version using RFID tags instead of colored plastic pieces.
Making the game as I have in the drawing would need at least an Arduino Mega because of the 4 RGB LEDS. I wonder if there is a way to multiplex, charlipex or somehow get the RGB LEDS to use less pins? (You need GND plus 3 PWM pins for each one)
I’m still thinking through how to make this and have gotten an Adafruit PN532 NFC/RFID Controller Shield.
So far I have 3 tags working. Holding each tag over the tag area will light up a different LED and play a different tone. We had seen the contact free jukebox a while back and liked the idea.
