Well, before we get started, I don't have much experience in electronics design before, so let's start together.
At first I used Eagle software, you can download it from here
install and open it
make a new project "hello.echo"
Right click and choose New schematic
Here are some commands you need:
- Add: to add new component
- Move: for moving and rotating
- Net: to connect the components together
- Name: Each point must be named to connect them easily
- value: for componentes values like "10K, 1uf"
before we start you need to add FAB_lib, you can get it from here
You need to put your file in a similar directory "C:\Users\zas\Documents\EAGLE\libraries"
Then go to library manager, and open "In Use tap"
then click on Browse, and choose your file(Eagle_fab)
now your library should be appear when you type Add command, If it does not appear with you, you can check the library manager
Now type "Add" command and choose UC_ATTINY44
left click on the workspace to put your component, and right click if you need to rotate it
press on Esc to return to the library again
Add the rest of the components with the same previous steps
type "Name" command and name each point
type "Net" command and connect the same points that bear the same names
