9/18 - 9/21

This week I finally fixed all the errors with my PCB. In order to test where the incomplete connections were, I used a multimeter to detect continuity, and where the incomplete connections were, I used wire to connect them to where they needed to be. The main three were the reset pin on the multiplexer, which needed to be connected to power, and three pins adjacent to it that needed to be connected to ground. I did also have to make smaller connections around the board to pins that weren't connected to power or ground as well. After making these corrections, there was finally continuity between all the pins on the board and I stopped receiving the error message that the multiplexer wasn't starting. After that, I soldered most of the other pins that I'll connect the sensors to, but not all of them because I don't have all of the sensors yet. In order to test these sensors, I used test code and checked that all the pins and sensors were working. I then started working on editing the code that I was previously using in order to accommodate for the change from a breadboard to a PCB and from different digital pins. I also need to hot glue the bottom of the board to make sure that all the solder stays in place.

Code that I need to update for the PCB
