Security Vault Attempt 2

I attempted to build another project which included an Arduino Mega instead of an Arduino Uno.

Unfortunately like attempt 1, although the diagram was simple to follow I could not get this project to work. This may have been due to the coding found for this project on instructables not working with the hardware correctly, the wiring as some wires looked as though they used T-Junctions which is difficult to re-create or the Arduino Mega board or components being faulty.

Unity Project 4: Ball platformer game

[Research] Traditional Poster Design (4CTA1214)

Image
As you can see from the superman poster, there are only four main colours used which includes red, blue, yellow and brown. All elements are filled in with block colours with no shading which was a common colour theme for traditional posters of this kind. This poster may have been used to advertise a new Superman comic or movie depending on the year it was created. The expression on the characters face fits the title shown on the poster explaining that he is returning. This poster advertised Coca Cola, and looks as though this specific poster was used in the USA - due to the currency used. The whole aim of the poster is to incorporate this drink into working peoples daily lives. This is seen by the slogan, 'Work refreshed' and the small graphics on the bottom right of the poster. Displayed is a man working in a factory environment and a lady is working in an office environment both drinking cola during their breaks - to feel refreshed. In some ways the bottle and
