Left hand Navigation panel > **EasyEDA Libs > Power Supply**
Hover over Voltage Source Icon (next to Battery Icon). (Or Current Source(EasyEDA), below battery icon)
Click on down arrow in lower right hand corner of voltage source icon > **Voltage Source(EasyEDA)**

Click on **Voltage Source(EasyEDA)**
Click on Voltage Source(EasyEDA) Icon (tip text now says Voltage Source(EasyEDA)).

Click on schematic canvas to place Voltage Source(EasyEDA).
Select voltage source on canvas.
Edit user parameters in right hand **Properties** panel (if not already open then click on far right vertical blue strip to open).

Available parameters for Voltage Source(EasyEDA) and Current Source(EasyEDA):
>Frequency: Freq(Hz);
>Wavshape: Function > dropdown list > Sin/Cos/Square/Triangle/Square
>Peak to Peak Amplitude: Amplitude(V) (Amplitude(A) for current source)
>DC offset: Initial(V) (Initial(A) for current source)
For more complex signal sources, select Voltage Source (Current Source) and see user parameters in **Properties** panel:

Some examples of these sources:
