I am working on an escape room game, the objective is to turn the lights on using push 6 pads {1, 1, 0, 1, 0, 1} 1 = on 0 = off and once those LEDs are on then the Magnetic Lock opens, currently the magnetic is always open for some reason.
I cant figure this out is someone could look at it with fresh eyes maybe? Maybe i missed a comma? I attached some pictures to show everything.
Any help would be amazing I think im just too new or too close to this to realize what im doing wrong.

The i in that for statement turns on italics in the IDE. causes the forum software to turn on italics.
if (digitalRead(switchPins) == LOW)
{
digitalWrite(ledPins, HIGH);
}
So everything after is in italics and your array indexes disappear. Read the how to use the forum stickies to see how to post code so that the IDE forum software does not screw it up. It is hard to evaluate code that is missing pieces.
if (switchPins == solution){
You cannot compare arrays like that. That actually compares the addresses of the arrays, not the contents and not what you want to do. Look up memcmp().

Is that really the your code. It will not compile as posted.
pinMode(switchPins, INPUT_PULLUP);
Is missing an indexer for the array, should be:
pinMode(switchPins[i], INPUT_PULLUP);
pinMode(ledPins, OUTPUT);
Same here. All the indexers in your for loops appear to be missing.
if (digitalRead(switchPins) == LOW)
Yup, indexer missing.
Did you copy the code from your previous post or copy from your IDE?
Serial.println(switchPins);
This will throw an error, too. For an array that is not null terminated, you need to print the array element at a time (use a for loop).
You say that the lock never closes. How are you powering it? Is it wired directly to the arduino, or is pin A0 connected to something that drives the lock?
@groundFungus - So I need to add (see below) to all of those basically? and no its not just mine I purchased the code from some one and thought I could modify it as it didnt work
[i]
Yes you need to add the indexers in the for loops where necessary. See the language reference for arrays for more information.
Here is the code with the indexers added where I think they are needed. I am not able to test the code as I do not have the hardware, but the code does compile.
