While you are routing a track, if you change the layer in the 'Layer' box at the top left hand side Eagle will place a via at that point and you can continue the track on the new layer.How to route LED resistor connector for double sided PCB ?
Confirm which component you want on the back side?Hi
I am practicing to design double sided PCB in Eagle .There is connector, resistor and Led on PCB board. I want to place LED and connector on top side and LED on Back side
I was looking a very small and simple example to design double sided PCB so I thought nothing is simple then the starting with Led's and resistor. I wanted to route component on both side that's why we called double sided PCBConfirm which component you want on the back side?
There is absolutely no reason to use a single via on that board. If for some reason you want both connections to a component on the back side to have its traces on the front, you need two vias. But to reiterate, vias are not needed.

No, First and second were on the same topics but This one was on the different topic.You now have 3 threads on this topic:

You don't need a double sided board for your circuit. If you want to just because you can, all you need to do is put traces on the top and bottom.No, First and second were on the same topics but This one was on the different topic.
I am sorry but I didn't wanted to mix all in one so created new for double sided PCB
Also note that through-hole mounting pads are through plated. Thus, whether you connect traces on the top or bottom planes, it makes no difference. Electrically, a top trace and a bottom trace connected to a through-hole pad are connected.You don't need a double sided board for your circuit. If you want to just because you can, all you need to do is put traces on the top and bottom.
In my version of Eagle, blue traces are on the bottom and red traces are on the top. You just set the layer before routing the trace. If you want to change the layer for an existing trace just use the change tool and change the layer.
I know that but I wanted to start with the simple circuit so I thought I should start with resistor, LED and connector for double sided PCBYou don't need a double sided board for your circuit.

If you want to try something a bit more challenging, try to lay this out on a single sided board (about 2.7" x 1.7").I know that but I wanted to start with the simple circuit
Yes definitely I want to make something complex and I have plan in mind.If you want to try something a bit more challenging, try to lay this out on a single sided board (about 2.7" x 1.7").
1) Making new devices is something you will need to do sooner or later. Sooner is better. Usually, you can find a suitable package. There is one for that chip in the Eagle library. Then all you need is a symbol and there are probably other 44-pin devices with the same pinout. If not, get something close and modify it. Then connect the pins to give your own device. Set up a personal library for those devices rather than add to an existing library. That library will grow.But the problem is PiC16f877A is not available in Eagle library so I searched on the internet and found that I have to create new library for PIC16F877A.
Do you use this site to get part ? because it say your connection to this site is not secure I have downloaded part from their websitesYou can get a ready made library for this part, and many other parts from:
