Research process

I was catching up on the progress while attending classes at school. It was a bit difficult to do the wiring manually for the first time. I felt so proud after finally laying out the board and getting it. The white color was really nice, but it was a bit messy once I soldered it. The software debugging was simply a grind (Q Shuan, It collapsed), the welding process went very smoothly, I like welding so much. Fortunately, I paid attention to the group messages every day and found that there was a problem with the capacitance of the touch button. I asked around at school to get a suitable patch. Finally, I discussed it with the teacher. I turned on the light (it’s difficult~), and finally came to the design of the PCB frame. First, I wanted to make a five-sided box (you can directly snap five PCBs together). When the bottom surface of this board was made, the protruding position was slightly slanted. , can’t get stuck, woo woo woo. Let's continue to improve it later. We have reserved 4 IO ports to see what else can be connected later.
