In Digital Media, we started this semester off learning about binary numbers. Computers are built from collections of switches which can be either on (1) or off (0), also known as binary numbers. On and off or 0 and 1, represent different letters of the alphabet. Each letter is assigned a number and the way that we were taught it, using little cards with different amounts of dots 16, 8, 4, 2, and 1 IN ORDER we create the number that the letter was assigned. We flip over the little cards that we don’t need and leave the ones that are necessary to making the number facing up. The little cards that are facing down are off (0) and the ones facing up are on (1). For example: The number 9 represents the letter “I” on the UTF-5 alphabet This is the rest of the alphabet When I first heard about binary numbers it sounded like it was a complicated confusing thing that I wouldn’t understand. Once Ms. Gottfried explained what they were and how to write using binary code everything started clicking. We used beads to make pins of our initials in binary code using purple for on and silver for off. It made so much more sense after doing an activity with it and was a fun way to learn about binary numbers. Also, using the little cards really helped because it was a great way to visualize the arrangement of the 0s and the 1s. Prior to this lesson on binary numbers, I did not know about binary numbers and I only had a little background knowledge on coding. Now I am comfortable using binary code to write words and I don’t need the little cards from before to help me. For our current project we are 3D printing jewelry with hidden words written in binary code using different symbols for on/off. I am excited to see how that goes!
