I loved learning about the microcontroller basics when I was studying. It meant I could start taking advantage of microcontrollers in my electronics projects. It kind of felt like with this knowledge, I was unstoppable. I could build ANYTHING!
And it is actually true. Microcontrollers are powerful components. They let you write programs to control your electronics. Combine this knowledge with how to build your own circuit boards, and you’re gonna make amazing things.
By using a microcontroller in your project you will have access to a vast amount of functionality from the tips of your (programming) fingers.
