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 : ()Īctually 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. The circle that you have pointed there is for 'drawing' what he is requesting is 'wiring'. These are also net flags, but show the 'direction' the signal is coming in or going out to some other device. > What are these little triangles in the final of each line? What means and how I can put it in EasyEDA? J1 pin 1 goes to Arduino pin Digital 0 and so on. J1, J2, J3, J4 are connectors, showing each pin having a connection off to somewhere on the Arduino board. These just tell the program, and show on the schematic, what connects to what without the use of long wires across the page. In EasyEDA you can also have them like that, see the _UserSupport_ post above.

> What are these circles in the final of every line? and what this means? How I put it in EasyEDA? These are the individual buffer gates as a symbol, but they are physically all inside one chip.

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. That means, when the pin is HIGH, that particular gate is off, but when it's LOW, then the gate is used. The dot for the symbol means that it's the OE(Output Enable) pin for that buffer gate, which is an active LOW input. You can use the triangle symbol or 'chip' style symbol, whatever works for you. The schematic symbol is a triangle with the circle. The '74AHC125' is a integrated circuit Quadruple Bus Buffer Gates With 3-State Outputs > What are these little circles together with this triangle?

Thank you for everyone who can help me!!ġ.

But I came across with some symbols in the PDF that I'm not understanding, can anyone tell me what the symbols below means and explain to me how I can put them in my EasyEDA schematic? That Would help me a lot!! This can be easy for some people, but I really don't know because I'm in the very beginning. Hello guys, I'm Natanael Prado and currently I'm trying to make my own schematics and PCB layout in EasyEDA, I'm using a PDF schematics from Proteus to help me with it (I only have the schematics in PDF format with me), this is my first time using EasyEDA and making a schematics.
