JOURNAL.md started + Hardware time!

• Created a JOURNALmd file
• Documented everything I did on the 5th and 6th of July, with photos and some explanations as to what I was doing and trying to achieve
• To make it short: prototyping and creating some visuals for the OLED screen/UI, as well as assembling everything together.
• Connected README.md to JOURNAL.md
• You can read it here
