Hi, me and my friend are making a school project where we are making an alarm.
The things we've used are a LED-display, a PIR-sensor, a piezo speaker and a keypad.
Basicly what we want to do is a functioning alarm that can be turned on and off with a code on the keypad, the led-display shows the current state of the alarm. The PIR-sensor will be used as the detector and the piezo speaker will turn on when the alarm is activated and the PIR-sensor sees movement.
The thing is that we've never worked with Arduino before and are quite frankly not very good at programming.
We have alot of code already though, which has all the basic features that we want with the alarm, but this code doesn't use the PIR-sensor or a keypad, it uses a photoresistor and 4 basic buttons instead. And we've realized that our knowledge in Arduinoprogramming isn't enough to make this work in the right time.
We would really appriciate if someone would be willing to help us with the code to make the PIR-sensor and the keypad work instead of using the four basic buttons and the photoresistor.

We're also attaching the code we've done so far.
