Arduino uno

Looking for assistance with the following simple project.

Arduino Uno:




Step Up Converter:

Electromagnetic Lock:

Basically, the goal is to use a keypad to control and electromagnetic lock. Entering the correct code will kill power to the output that we have the lock hooked to, the circuit will be broken and the lock will release.

The LCD will display the PIN that is being entered and simple messages such as "Enter correct PIN", "Incorrect PIN, try again" etc.

You can find many projects like that online if you look well.
