Code Arduino for me -- 2

Hello, I'm an control and automation engineer from Turkey. I am using Atmel processor based Arduino boards all the time for my projects. I checked out your attached file and i see that you want to use a speaker for this project. Since Arduino boards have a limited current output driving speaker outputs is not a preferred way. I suggest you to use a buzzer (which is a basic electronic whistle) or add another part to use mp3 files with Arduino. Another advantage of using mp3 is you can add very cool sound effects to your system, like starwars door opening sound or any sound effect you want. I made a similliar lockpad to a CS-GO fan with bomb defuse sound effect on it. Locking algorithms are very commonly used in automation projects, so i think it wont be a problem for me. I can finish it in 2 days.

Hello, I will do simplest coding in C language for Arduino. It looks like an assignment so coding will be easily understandable. I have created a Keypad Door lock system with Arduino using LCD panel , keypad, servo motors. I have also done many similar works and will provide the Code and circuit simulation diagram. Lets have a chat for further details and budget. Thanks.

hi there i have done a music player project from arduino in past so i can easily do this keypress and led are normal thing latter on you can just replace it with Solenoid or relay to unlock door please msg to discuss in detail.

Keypad door lock systems is a very sophisticated device. I've worked on a project same as this with arduino itself. So i know how to build it for you.. I'm new to freelancing but a experienced embedded engineer for 5 years.. I can build you this project within time and with great quality.. I'll also provide support for afterwards if you face any problem with it.. I would like to know more about the project.. you can txt me for any doubts, really looking forward to work in this project...

To connect a 4*4 keypad to an Arduino is pretty easy and straight forward. I will use the tone library to provide a tone for each key. When correct sequence is pressed the LED will light up. However, I haven't the specs of LED you have so I cannot figure out it's wiring but that a small task. please get in touch and I will have this sorted in a few hours. Am looking to working with you. Regards.

As per my knowledge in C as well as on arduino, We can make this thing up and running as per the requirement, also previewed your PDF and its great to learn as well as to know it more deeply, will make this, kindly approach me thank you.
