Arduino Mega would be able to handle this. over 30 I/O pins available on this board, however it is nearly 2x the size of the Uno. You could buy a knock-off version from china for fairly cheap (roughly $10-12)
the problem you had with your board is your 470 resistor is positioned incorrectly. You have it going from pins 5 -> 6 when it should be going from pins 6 -> 7...
My God, millennials these days... always looking for free handouts on silver platters for the work they should be doing, along with their "participation" ego awards for last place. A thesis is not supposed to be easy or a walk through the park. If it is, then you have chosen the wrong subject as your thesis. It is meant to be something for intricate research, development, theory, and hard work.
My grandfather use to be a locksmith and gave me a very valuable tip. he used to use graphite shavings from the pencil to lubricate the keyhole on any door handle, deadbolt, or padlock. You just have to make sure that you don't include the wood shavings, and that the graphite in the pencil is at least a 2B or lower grade. pure graphite in powdered form is best, but pencils will work just as well.
