Locked Box Arduino Project

This is the circuit diagram that I followed on instructables.

Unfortunately the keypad I used was slightly different compared to the one used in the locked box project on instructables. The key difference is that the keypad uses a 3x4 keypad while I am using a 4x4 keypad configuration. Therefore I have had to adapt my hardware and code for these differences. 

This image was taken before the code was edited however the Arduino responds to some keypad presses and the green LED shines. Therefore as this was quite a positive result, this convinced me to pursue this design.

Logo Design

Image
I specifically wanted my logo to be an SG as these are my initials. Therefore I attempted to a few different designs until I found the one that I liked. For this post, I have put my logos on blackgrounds so that they are visible. This was my original logo however I wanted to change this slightly as I feel as though it didn't fit the feel of my website and was too simple. When creating this logo, I took into consideration my background and the type of style I wanted to go for. I was inspired by my favourite game FEZ as I really like what they did with the title of the game. If you look at their logo closely you can see the logo from both angles and really liked this effect. I decided to put the S and the G at different angles as it resembles a butterfly. When you see my logo from a different angle it looks as though a butterfly is flapping it's wings which I believe fits well with my background. I played around with the design of my previous...

Bootstrap Template

Image
I decided to use a bootstrap template for my website as I thought this may have made elements faster to implement as the template would already be responsive. I researched the benefits of using bootstrap and according to Christopher Gimmer in his 2014 blog 'Top 5 Reasons to use Bootstrap', he stated in his conclusion that, "...there are several benefits to using Bootstrap. The framework allows for rapid, responsive development that is consistent and well supported by the development and design community." His five reasons were, "Speed of Development, Responsiveness, Consistency, Customizable, Support" which I understand and agree with and therefore believe it is beneficial to use bootstrap in this project. This specific bootstrap template was similar to my mockup design and therefore by editing the code this template could look similar to what I had designed and invisioned.
