There are some software available to emulate mouse clicks online, some free and some paid. But sometimes the best way to do it is just to use a simple script. It's light, and it does not require you to install any suspicious software, so you are in control of what it does.
I had the need of emulate mouse clicks on Windows to automate some boring stuff I had to do, so I created a simple script to click on stuff for me, and I decided to share it with you.
