In this video, I build a simple step-down circuit using a 7805 regulator IC. This circuit can be used to reduce the voltage from a 12V battery to a stable 5V output via a USB port. It's perfect for electronics that require a 5V voltage but are powered by a 12V source. Components used: AN7805 Regulator IC (5V) 470uf Capacitor USB Port 12V Battery as a power source Hopefully, this video is helpful for those of you who want to learn basic electronics.
