In this month's group activity, I was mainly responsible for the partial soldering of PCB board and cutting with the sanding machine. After completing this part of the task, I opened the sample code for understanding and modification.
Before my team mates soldering, I also prepared the necessary components for them to make their work more convenient.
Of circuit PCB by soldering, inspection found that a resistor connected to the transistor used the 100 k ohms, this was a mistake, we immediately changed it to 100 ohms.
All in all, for the final day of the semester, I believe the Lima team will score a great victory!
