Hi all, I am currently a web programmer. And i am been approached by a guy who came out with an idea to rent a study area for students to study.
There is already a website in place and we have configured to receive payment thru paypal for a slot.
In order to only allow paid students into the study area. my friend suggested that the website to generate a pin for the student to go in and out of the study area.
We are hoping that to install a keypad outside the study area to allow the student to key in to go in and not allow any other people from using it to go in until the pin is entered on the other keypad within the study area. The study area is secured with an existing EM lock and the electrician is telling me to just cut the power to disable the lock and the door will be open.
I am thinking of adding a microcontroller where my website that is in other server room will send the generated PIN of the customer to the microcontroller via Router *** port forwarding.
Each PIN will have a slot indicated on start date and time. The Keypads that are outside and inside would have a LED to show the customer whether it is keying in correctly.
As I am new to electronics, i will need help in these areas:
Should i use a relay to on off the power to the em lock.
Should I use Arduino for this project? Is it possible to attach the microcontroller to the power line without a 5V power source?
Can i add Wifi module to the project? If can, how do we connect to the router via IP address?
How do I install two keypads on to the arduino project?
Should I go via a different approach to solve the problem?
