N.B: I'm still a 14 years old boy that is just a beginner in electrical engineering.
I started a project with my Dad which was a "matrix clock." We used 3 red LED matrixes which are driven by several 74HC595N shift registers.
We made the code, uploaded it to a micro-controller, tested it on a bread board and it works sucssesfuly.
When we started designing the single sided PCB we decided that we would just do a module of three LED matrixes aligned together connected to shift registers, so that we can use it as a screen for any thing, not just for the clock.
We used Easyeda as it is the most famous online schematic & PCB designer.
I made a schematic and converted it into a PCB, layed out the parts properly (as I think) and started auto-routing (as it is very hard for me to route each connection manually.)
Remember that: I am using single sided PCB.
Every time the auto-router fails to route, even when we changed the layout of the elements.
At this point we got stuck, and we don't know what to do.
Does anyone have any suggestions?
Edit in Question : If there is any components required like jumpers, sockets, wires, etc. it will be nice to tell me how to use them.
This is my schematic.
Very bad. I'm sorry, still learning.
Edit in question : This is another schematic I did today, no difference in connection but the difference in arrangement, color and in the data header (I hope you understand me more clearly via this image):
This is one of my PCB layouts:
If there are any suggestions please tell me.
N.B: Sorry again if the homepage isn't properly setup because I don't know yet how to use Easyeda.
Here arecsome project links on the website so that you can access the PCB & the schematics and see them lively:
