when you create a new symbol, you can place a circle,  for netflage, you can find at EElib 

Hello! Welcome to the club! > What are these little circles together with this triangle? Is it some kind of connection? How I can reproduce it in EasyEDA? The "74AHC125" is a integrated circuit Quadruple Bus Buffer Gates With 3-State Outputs Link to datasheet: [https://www.ti.com/lit/ds/symlink/sn74ahc125.pdf?ts=1594706572066](https://www.ti.com/lit/ds/symlink/sn74ahc125.pdf?ts=1594706572066&) The schematic symbol is a triangle with the circle. You can use the triangle symbol or "chip" style symbol, whatever works for you. The dot for the symbol means that it's the OE(Output Enable) pin for that buffer gate, which is an active LOW input. That means, when the pin is HIGH, that particular gate is off, but when it's LOW, then the gate is used. You can also see that there are multiple triangles like that in the schematic with U1:A, U1:B, U1:C, U1:D next to them. These are the individual buffer gates as a symbol, but they are physically all inside one chip. > What are these circles in the final of every line? and what this means? How I put it in EasyEDA? These are Net flags. In EasyEDA you can also have them like that, see the _UserSupport_ post above. These just tell the program, and show on the schematic, what connects to what without the use of long wires across the page. J1, J2, J3, J4 are connectors, showing each pin having a connection off to somewhere on the Arduino board. J1 pin 1 goes to Arduino pin Digital 0 and so on. > What are these little triangles in the final of each line? What means and how I can put it in EasyEDA? These are also net flags, but show the "direction" the signal is coming in or going out to some other device. I hope this helps you! Good luck!

@UserSupport Hello ; The circle that you have pointed there is for "drawing" what he is requesting is "wiring".   :) Hi Natanael ; regarding your request let me first invite you to read the "getting started" guide to learn the basics of "the UI icons functionalities" through the following link : [https://docs.easyeda.com/en/Introduction/UI-Introduction/index.html](https://docs.easyeda.com/en/Introduction/UI-Introduction/index.html) > What are these little circles together with this triangle? Is it some kind of connection? How I can reproduce it in EasyEDA? Actually you don't have to reproduce these circles since they are just indicating how the integrated circuit operates, you are using a Noninverting Buffers 74HC125 which has Quad gates, in Proteus when you select that component you will gate the gates separated each one aside so you can drop them one by one to create the complete integrated circuit, in your design already you have the four gates labeled (**U1**:A , **U1**:B, **U1**:C, **U1**:D) and they are the four blocs of the **U1** 74HC125 then you have (**U2**:A , **U2**:B, **U2**:C, **U2**:D) belong to **U2** 74HC125. In EasyEDA it will be just a little bit different because you will get the four blocs together in one part with all the pins in one bloc, so you don't have to reproduce that circle :) > What are these circles in the final of every line? and what this means? How I put it in EasyEDA? The circle that you are describing now in Proteus it is the **default terminal** (could be Input, Output BIDIR, Power etc..) you can reproduce it in EasyEDA using the "net label" from "wiring tools" palette (please check the link that I posted above to understand how to find/use the wiring tools) > What are these little triangles in the final of each line? What means and how I can put it in EasyEDA? In Proteus these are also terminals (similar to the circles that we talk about in the previous question) the only difference is that these are not default terminal (not circles) but they are Inputs or Outputs terminal just to make the schematic clear to understand which are the inputs and outputs terminals, in EasyEDA we don't have such tool but These are also could be represented as "net label" or "net port" without any problems :) I advice you to read more about both Proteus and EasyEDA before getting further in your project, and I will be here in case you request support. Keep up and best of luck.

@deskpro256 Thank you for your answer, it have helped me a lot, I'm very glad!!! 👍🏽😃

@UserSupport Thank you!! I appreciate your answer, very helpful!!!

@JLCPCBsupport Thank you so much, Now I can understand it!!! ✌🏽😊

@Natanaelprado, It will help you to read: [https://easyeda\.com/andyfierman/Welcome\_to\_EasyEDA\-31e1288f882e49e582699b8eb7fe9b1f](https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f) and all the documents that it links to, in particular, (1), (2.2), (2.3), (4) and (6).

@ JLCPCBsupport @deskpro256 Also, I would like to know where are the +VIN and the 3V3 supply flag, I couldn't find it in EasyEDA.

@Natanaelprado, Place a VCC or +5V net flag from the Wiring Tools palette then rename it.  Basic skills like this are all explained in the EasyEDA Tutorial. It will save you a lot of time to read this and the linked documents that it points to: [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)

@andyfierman Ahhh ok, I was imagining that I could do this but I was afraid if this could be a mistake in my schematic project. Thanks a lot!!!
