Can you help me see if this resistor array is reasonable? The resistor array is connected to port p0 as a pull-up resistor and leg 1 is connected to the power supply. Then can the holes of the dot matrix and the resistor array be connected to the bottom line at one end and the top line at the other end? As shown in the picture, some holes of the dot matrix are connected to the red line and some are connected to the blue line. Is this possible?

Um... This question should not be asked in this way. It seems that you don't understand why there are blue and red lines. The top layer is red, and the bottom layer is blue. They are all connected. They are just on different layers. Just run the lines normally.

If it is a through hole, you can route on the top or bottom layer. If it is a patch, you can only route on the corresponding layer of the patch. If you want to switch to other layers for routing, you need to drill a through hole to connect it.

I see the resistor at port P0 has been connected. Remember to connect one port of the resistor to VCC.

Actually, I just started learning. I know that top is the top layer with red wires, and bottom is the bottom layer with blue wires, but I am not sure and I am afraid it will not work. This is my first time drawing a PCB board

It has been connected to the VCC of the 51 microcontroller.

OK, OK, got it.

Beginners must remember to understand the concepts of each function first, so that you can get twice the result with half the effort. You can look at the top post in the PCB section, the recommended post for beginners.
