yesterday i started my first solo project on my Arduino Uno. I tried to use my keypad (4 rows, 4 columns), my LCD, a servo and two LEDs to make a safe mechanism that triggers the servo whenever the right code of numbers is entered and switches from a green to a red LED.
I found some similar code online and modified it by tweaking it here and there and adding some stuff (the whole servo library for example).
As soon as i upload the sketch to my board it is ready to use and it works, but here comes my problem: it works only once...
I tried to fix it a few times, but to be honest i don't know a lot of the programming syntax the original author used.
As i figured out before: this is my first real solo project on that topic and i would really really appreciate some help. So if you, dear reader are able to help me out in this situation i would be amazingly pleased if you could get me some advice, tips and tricks or even a direct fix of the sketch.
