I wanted to learn more about electronics, and I found this https://www.open.edu/openlearn/science-maths-technology/an-introduction-electronics/content-section-0 to start from so I can have a grasp on theories first, and I want to try learning microcontrollers afterwards but I can't afford to buy any IRL atm, are there any softwares to simulate them to assist on learning without having the physical hardware? I'd be happy if anyone could give me any tips toward that, thank you if you read this far
