The red joint dot shows when two or more wires or a wire overlaps or crosses a pin. When a wire joins a pin but does not cross it or overlap it, there will be no red joint dot. So your wire to resistor pin junction indicated by your left hand arrow is correctly joined. The right hand arrow shows an incorrectly drawn junction where the wire overlaps the pin. Wires should not be drawn overlapping pins. Please see (2.2) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) for more information about good practice in drawing a schematic.

If what you say is true, why does the resistance seem to be connected in the hand that you say is incorrect, and not in the hand that you say is wrongly connected? in the PCB !!! Do I understand from your words that the connection point is automatic? That is, I cannot control whether or not it is placed I'm so desperate, I'm planning and executing good and complex circuits and then I stand in front of the connection point and find the scheme is completely different in the end than pcb at the end !!!

Your posts show that you are using Chrome 75 on Chrome OS and Chrome 96 on W10. What version of Chrome are you using when you draw the schematics?

In your schematic screenshot, both nodes that you indicate should be joined correctly. All that is wrong is that the right hand join shows an incorrectly drawn joint which creates an unnecessary red joint dot. The schematic screenshot does not show enough to be clear about the start and end points or where the nets go to and from and the prefix of the transistor is not clearly shown. Your PCB screenshot does show that one end of R2 appears to be unconnected but it does not show enough of the rest of the PCB to be clear about how this relates to the schematic. The PCB screenshot suggests that the Symbol pin to Footprint pad mapping of Q1 may be incorrect but since Q1 is not identified in the Schematic screenshot, this is uncertain. * Are you sure that all the lines you think are wires are in fact wires and not just drawn lines? * Do the wires snap to a grey dot at the pin ends when you draw them? * Your project is private so only you can see it. * If you make it public then others may be able to offer more useful help.  * It may help you to read: [https://easyeda.com/forum/topic/Understanding-Ratlines-371bdbf646c54b23a57451eb05b2026d](https://easyeda.com/forum/topic/Understanding-Ratlines-371bdbf646c54b23a57451eb05b2026d#:~:text=They%20show%20which%20pins%20are,few%20times%20you%20see%20it)<br> <br>

Hi! Drawing the schematic into more understandable and fluent makes sure that your PCB design becomes much more easy to do. I suggest watching the video from Eevblog: [https://www.youtube.com/watch?v=R_Ud-FxUw0g&t=1496s](https://www.youtube.com/watch?v=R_Ud-FxUw0g&t=1496s)<br> <br> Regards, Markus Virtanen HW / Electronics Designer

Well, there are several things I need to clarify here: 1- In this video, specifically at the time 3.35 A circuit that I designed and implemented on Protues appears. Because of an idiot who destroyed my computer, I used the laptop to work, but the Protus program needs more hardware than my laptop's capabilities, so the emulator does not work well (simulation) That's why I came here, and decided to do the rest of the work, the program here is easier and faster and the simulation is good but this simple point ruined everything. I was supposed to add a power circuit that works on a current of 220 volts and feed the sensor circuit with 5 volts and integrate it into the design instead of using a mobile charger.

I will try to go back to proteus or start here from a new one

@mo-salama, From the PCB screenshot, there seems to be nothing unusual about your design. If you can either make your project public or add me to your project then we can help you successfully complete your design in EasyEDA.

Although the views are incomplete, from the screenshot of the EasyEDA PCB compared to the Schematic, I have a suspicion that the schematic symbol for U2 has its pins in the wrong orientation so that the snap nodes are at the inside ends of the pins instead of the outside ends. Hence although the wires to the pins on U2 are drawn to the ends of the pins, they are not actually connected to the pin snap ends. See (2.2) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br> or: [https://docs.easyeda.com/en/SchematicLib/SchLib-Create/index.html#Pin-Attributes](https://docs.easyeda.com/en/SchematicLib/SchLib-Create/index.html#Pin-Attributes) for more information about this

@mo-salama, If the above situation is true then, because you are the only one who can identify U2, please submit an error report for the symbol using the **Report Error** tool.
