December went fast, we started the month by Llewellyn finishing the soldering for the PCB design which was drilled by Josh, then we tested the IR sensors, it didn’t work first time, I had to adjust a bit of the code but it wasn’t too much of an issue and sure enough, after 2 labs, the code was working and we installed the PCB in the chassis and it run perfectly, after several tries to make sure it was going straight, and to make sure the obstacle avoidance worked, we did the test and passed with flying colours, and that was the end of the semester.
