Thanks to the EEWORLD community for organizing this follow me event. Although my profession is a web developer and the delivery time is a bit tight, through the learning and practice of this event, I met a group of like-minded partners here, communicated with each other, and grew together. I understand the use of Python in the circuitpython environment and the calls of some common libraries, which helps me better operate the functions on the development board. I look forward to the next event. # 3.
