Music: 2011 Lookalike by Bartlebeats Killing Time, Kevin MacLeod (incompetech.com) In this project I will show you how to create a simple circuit that can interrupt the current flow to a load when the adjusted current limit is reached. That means the circuit can act as an overcurrent or short circuit protection.
