What did you personally accomplish this week on the project? Give files or photos that demonstrate your progress. Prove to the reader that you put sufficient effort into the project over the course of the week (12+ hours).
This week I worked on getting the upload 4 words to the row working and creating a test bed for a grid set up. While I was trying to get a row working I felt that our testing setup was inefficient and a bit messy so I decided to layout the initial grid. I worked on creating all the slots for the blocks and wiring everything up so that we can test code more easily and also show our proof of concept. Also I finished soldering the rest of the wires for another 5 sets of male (grid) pogo pins as well as 3 more female (block) pogo header pins. With this set up, it helped us to identify and create a testing plan as well so that we can figure out what components may not be working as intended. We found a few pogo pins that needed to be resoldered as well as some picos’ UART lines were broken and we had to switch to a different set. We ended up using UART0 on pins 16 and 17 and I worked on soldering on the female header pins and wiring those to female pogo pins, which allowed us to get a 2nd row of blocks working. I tested our embedded controller and ensured that we were able to get all 8 blocks working with our upload_words function. I also worked on filling out our testing sheet and testing components individually via continuity test to isolate any parts that need to be re-done. I originally had wanted to work on laser cutting and the 3D component holder this week but instead switched gears to the grid set up as I felt that was more of a priority for us to be able to reach our goals.

Is your progress on schedule or behind? If you are behind, what actions will be taken to catch up to the project schedule?
I am currently on schedule and a little bit ahead as I was able to get to the building of a prototype grid that is a good test bed to test/finish out the software side of our project.
What deliverables do you hope to complete in the next week?
I will print out the 3D component holder, laser cut the on/off switches, and work on thoroughly testing our code end to end (E2E).
