This was the task and the wirtten code is below. I need someone who can correct the code so that the points in the task are fullfilled:
Topic: PIN encryption
Description:
We intend to create an encryption for a safe. For this purpose we want to use a hardware
use, on which we can enter a PIN using buttons. With these buttons we can open or close the save.
Here you have three attempts for the correct input. If all three attempts were worng,
there is a possibility to unlock the safe using master code.
Changing the PIN (new PIN) is possible without big change of the program.
To enter the PINs we have three buttons and a button for confirmation. In total 4 buttons.
Each button can be pressed four times. If a button was pressed four times the program will start again from the beginning.
The three PIN buttons must be pressed in sequence. If the specified code is correct, a green light on the hardware (means a lamp) will light up.
If the PIN was incorrect, so another indicator lamp will light up red. If the PIN is entered incorrectly three times, so
the red light will blink continuously and an alarm is triggered. Now you can use the
Master code to open the safe and stop the alarm. The master code can not be changed and
is defined only once. It is sufficient to enter the same code again and confirm to close the safe again.
What is needed:
- Hardware
- Two light
- 4 buttons
- Alarm System
I attached the code I have written.

Hello
According to your job requirements, I have done many projects like yours.
Main is my own SmartHome on arduino.
I have applied to this particular job because all the requirements of this project are in favor of me and I can 100% assure you that I must be successful in this project and satisfy you. I never apply to any job what doesn’t match my skills.
I'm always online on Skype or phone.
Let me know if you decide to hire me.
Thank you and have a nice day !
Hi,
I went through the description and the program attached. The program doesn't seem to fulfill all the intended task the code is also subpar. I can write the entire code from scratch for you completing all the requirements mentioned. Please have a look at my profile, you will find I am apt for this project. Looking to hear from you.
Thanks,
Anu
