+    "While the above setups allow you to control the behaviour of an LED using a switch, they don't allow for more advanced logic to be implemented. For example, in your version of Whack-a-mole, LEDs should turn on at random, much like how moles randomly appear from holes in the original game. Further, analogous to hitting the mole with a mallet, when the corresponding switch is pushed, the LED should turn off. \n",
