Cadsoft EagleCad Tutorial Lesson 3

Lesson 3 in my EagleCAD tutorial series. In this lesson we will start a schematic for a real working circuit. In this case, a voltage regulator, filter caps and an LED. We will cover some new tools, point out some quirks of Eagle and pitfalls to avoid.

Before I highligt an error, I would like to thank you for taking the time to do the videos. Very helpful!!!

I suspect the power jack is reversed. The center pin is usually + on the vast majority of power adaptor supplies. Good that you have a diode in series!

Actually, I should have pointed out that that particular library is ass-backwards and I have to connect it the way I showed for it to be properly connected. If I did'nt the center pin would be negative. My only guess is, this was created by someone in Europe and they tend to like reverse polarity.

hey thank you Jason,

because of your lessons I was able to design my project for the circuit course using Eagle instead of using note and pencil

I'm waiting for more lessons.

I'm wondering if I can use Eagle to test the output of my design (simulation) and if I can do it could you please show me how ?

Great to hear! I am wokring on more lessons to upload, but I am having to find time between my day job and running a seperate company.

To potentially help someone else out, make sure you use the netlist button to draw connections from one component to another. The line to use just used for general marks.

thanks man! really cool!

It is strange that CadSoft manual tell us to use the NET tool (3rd symbol from the bottom on the toolbar, looked like a greyed out and bent toothbrush) to connect parts. However, you tell us to use the LINE tool. I got a lot of errors using the line tool even if i connected them but after learning about NET tool, i got it right.

This is a very important function that i think you must correct. Frankly, i have reason to doubt your skills when you teach such fundamental errors.

@rpcelectronics there was indeed a mistake on the symbol but on the actual pcb trace its accurate, believe me i tried and already used it a couple of times now

I made a circuit in Eagle and now I want to make physically on a breadboard but it's too complicated to figure out where to put all the pieces - chances are I'll screw it up. Is there now way to make Eagle automatically figure out the locations?

i want to learn what all this means so badly but i must wait........ untell at least 10th grade

Thanks a lot!

What's the difference between "wire" and "signal"? Thanks! Great vids!

[schmarden]

Thanks man!

Cool, I can teach you something, hit ESC on the keyboard to exit a tool instead of clicking move or double clicking a wire end
