PCB DESIGN THROUGH EAGLE SOFTWARE
[attachment=51675]
How deals with the PCB editor: EAGLE
I will show you , how to use EAGLE with the use of example , which is given below:
A circuit employs a 555 timer IC to generate a square waveform, a potentiometer to adjust the audio frequency of the waveform, and a transistor circuit to enable the waveform to drive an 8 ohm speaker.
Add Circuit Components from Pre-defined Parts in Library
Now, click the Add button in the command toolbar on the left-hand side of the screen. You will be greeted by a window that shows a list of libraries which contain predefined parts that can be used for schematics and boards.
In the window below, the rcl library is highlighted. This library contains various packages of resistors, capacitors, and inductors.
Clicking alongside the R-US_ designation will open the menu of American-symbol resistors.
Make Schematic Connections
Now to interconnect the part of schematic, click on ‘Net’, (which is located on the bottom of the command toolbar.) according to our ckt diagram.
Make an Electrical Rule Check of the Schematic
Once we have completed the schematic, the Electrical Rule Check command is invoked to test it for electrical errors.
Simply click the Electrical Rule Check button, located at the bottom of the command toolbar. A pop-up window will appear containing a list of the errors and warnings.
Clicking on any error or warning in this list causes a black box to appear in the schematic editor window to highlight its location.
