If you want your valentine to work for their candy hearts why not build them a slot machine to let them win them. I have seen little bits before but this is the most complex device I have seen built!
“Try your luck with the littleBits Slot Machine and win a handful of candy hearts for your special someone. This slot machine operates just like the real thing. Pull the lever to start the graphics spinning on three DC motors. As they stop spinning in succession, win big when three hearts line up. When the hearts align, so do three bright LEDs and three corresponding light triggers. This signals the servo-activated trapdoor to release a candy jackpot.”
