How to automate similar actions in windows?

Question

Automation

The work program has many operations of the same type that are associated with data entry.
Also, you can’t install third-party software on a working computer, as well as climb into the program algorithm.

We need a script that will repeat the cycle of the last entered 3-4 steps, n-th number of times with a certain interval between steps. Something like a batch file.
To approx.
1) Reading a barcode scanner (13-digit number). Wait 0.5 sec
2) press the enter key. Wait 0.3 sec
3) press the f1 key
4) repeat the last 3 steps n-1

Need advice on how and where to implement such scripts, where to look, what to learn.

PS I don't understand programming, the most I can do is write a simple script in js.

AutoIt

Answer 2

If you can’t install software, then you can build a keyboard emulator on Arduino.
