Mind Trainer — exercise your mind in an enjoyable way! Our PIC powered puzzle is quite simple in principle but requires a good deal of thought. It's based on an old brain-testing game normally played with coloured pegs (similar to the classic 'Mastermind' game). Two players are required, one of them being a 'dummy' — in this case, you pit your wits against a PICmicro microcontroller.
