People wonder: "Why does the switch lock up when I press it?" Answer: The switch locks up for 2 seconds after you press it. If you press it when it's locked, you have to wait 2 more seconds. This is so it doesn't confuse the program and so you can't spam the button. People also wonder: "Why doesn't it do anything when I click the number buttons?" Answer: Turn on the switch. Then it completes the circuit and makes it work. People also wonder: "Why does it say ERROR in the top left corner randomly?" Answer: It's actually not random. It does it whenever the switch is locked in case the code when crazy and for some reason made the switch lock. People also wonder: "When the volts reach 12, why does it show random stuff?" Answer: It's actually not random. It's supposed to show letters, but it's on a 7 segment LED display which is not designed for showing letters. 14 segment and 16 segment LED displays are designed for showing letters AND numbers. So the volts sign is (Supposed to) say MAX.
PLEASE READ THIS!!!! Please note that the switch doesn't act right at all if you click it and then click it again within less than 3 seconds. The question mark in the corner is also kind of glitchy??
