Now that the software is debugged, the indicator light of D4 cannot be lit, what is the problem? Is there any problem with the hardware circuit? Thank you!

Is the number of resistors not enough?

LEDs in parallel are more current and difficult to control

What is the specification of this lamp, you can try a small current lamp, and this circuit is a bit laborious. -4 more IO wasted

The resistance value should be adjusted, some LEDs are connected in parallel and some are not connected in parallel.
