Hey
Below is my code for a project i am doing at school. I am having trouble getting the LED's to do what i want them to do and was wondering if someone could 'verify' that my code is correct. What the LED's are doing are just turning on and staying on even when i unplug the switch i am using from the power. I am using a 12 position rotary switch which is why there is so many pieces of code.
I am quite new to this so please try to make it easy to understand.
Thanks
