Watch the Video Tutorial: Draw Circuit Free with EasyEDA
EasyEDA is a a great and above all free web based circuit design, simulation and printed circuit boards (PCB) design tool for electronic hobbyists, engineers, teachers, students, makers and enthusiasts. In this article we are going to learn how to draw an electronic circuit for free using EasyEDA.
- With a quick google search, type the keyword: “Draw circuit“,
Figure 1: Type the keyword “Draw circuit” in Google search engine
- Select “EasyEDA – Online PCB design & circuit simulator“
Figure 2: Type the keyword “Draw circuit” in Google search engine
There’s no need to install EasyEDA software all you need is just open EasyEDA in a web browser. EasyEDA has all the features you expect from traditional electronic design automation (EDA) softwares like OrCAD, Altium, DipTrace among others, this tool easily takes your design from conception through to production.

And many more.
Creating a new Project
You can start a new project right away but clicking on “New Project” on the top right-hand corner of the screen. Click on Login, if you don’t have an account you’ll create one for free. You can also login with your existing Google G+ or QQ account. In your account you can manage all your projects, components, personal settings and many things.
In this step, you can create a new project either Public project (Only you can modify this project. Any one can see it) or a Private project (Only you can see and modify this project).
You can create a new Schematic, a new schematic Lib, a new spice symbol, a new PCB and so on.
- On the left-hand side, you can select your components symbols you want to place.
- Just click to select an object then click on the canvas to place it.
- You can move around the component where you want to place it.
- Click the mouse right button to deselect
- In the filter section, type the name of the component that you are looking for or you can click on More Libraries at the bottom to browse and search hundred of thousands of components.
- When you select a component, on the right-hand side in device manage you can change its value.
- Join the components with wire (Hotkey: press W) and complete your circuit.
- You can also use the Wiring Tools to select various wires and electrical connection points. Hover your mouse over each tool, its name will appear. We have a wire tool, NetFlag GND, Voltage probe, Bus, Net Port, pin, Bus entry, NetFlag VCC, Group/Ungroup symbol, Net label, NetFlag +5V, No Connect Flag.
- If you prefer to use shortcuts, you can click on Hotkeys settings to see the list of hotkeys, you can also modify the combination of your hotkeys as shown on figure 7 below.
Below is a simple circuit diagram we have drawn, a DC motor controller L293D Interfaced with a PIC18F45K22.
Figure 7: DC motor controller L293D Interfaced with a PIC18F45K22
We used the Net Port to connect each end points instead of joining wires criss crossing each other, in this way the desighn will look very neat.
One you done, you can save your data in the the cloud by clicking on the save button. You can also export to PDF your circuit diagram as well by clicking on Export.
Figure 9 below shows an exported PDF file of the schematic.
