Five LEDs Puzzle
Press the buttons in the right sequence to light up all the LEDs. Each LED lights up briefly when you press the corresponding button below it, but an LED only stays lit under certain conditions; to solve the puzzle you need to work out what the rule is.
For more information see Five LEDs Puzzle PCB.
