Let's build a simple high-pass filter!

Components (in libraries):

1 resistor

1 capacitor

1 ground

2 solder pads (I/O ports)

1) Start Eagle

When you start Eagle the Control Panel should pop up.

2) Create New Schematic

• To create a new schematic go to File -> New -> Schematic

3) Add a resistor

• Go to the Control Panel. Expand Libraries -> discrete.lbr -> RESUS-5. The library folders are organized by functionality and by manufacturer. Some symbols may be European and some may be US. RESUS-5 is the US symbol for a resistor.

  When  RESUS-5 is selected two figures will appear. The figure on the left is how the resistor will look in the schematic view and the figure on the right is how the resistor will look on the board layout.

  When selecting a component in a library you may notice one of two symbols next to the name of the part. A parts symbol means that Eagle provides both the schematic and layout for that part. The other symbol is a layout symbol which means that you need to make this component.

• Select ADD then left-click (on mouse) to place the part. Another window may pop up, just select Cancel. Press escape (Esc)  to exit out of the mode.

• Set the name of the resistor by choosing the Name button . Set the value of the resistor to 10k with the Value button .

• To move the part you can select the Move button .

• To rotate the part you can select the Rotate button and click on the object you wish to rotate.

4) Add a capacitor

• Go to the Control Panel. Expand Libraries -> discrete.lbr -> CAP-5.

• Then add the capacitor and label it with 0.1uF as in step 3)

5) Add Ground

• Go to the Control Panel. Expand Libraries -> supply1.lbr -> GNDA.

• Then add the ground as in step 3)

6) Add Input/Output ports

• Go to the Control Panel. Expand Libraries -> solpad.lbr -> LSP11.

• Then add the I/Os as in step 3)

7) Connect (wire) the components

• Arrange the components using the move and rotate buttons.

• Here is a image before the circuit is connected

• To connect the components use the Wire button . Hit the escape key to get out of the wire mode. To create an explicit junction use the Junction button .

• Here is an image of the circuit wired up in the schematic.

Make sure to save your schematic!

Now you are ready to go to the board!

Delete: To delete, click on the (X-button) Delete button then click on the object you want to delete.
