2pcs 9V DC Battery Power Cable Plug Clip Barrel Jack Connector for Arduino DIY

[Music] so this is our 2.1 millimeter power plug that plugs into most of the jacks that I put on our projects - it's connected a 9-volt battery clip that clips on to the end of a 9-volt battery in this video I'm going to show you how to properly connect the wires to the 2.1 millimeter plug today we want to use this 2 point 1 millimeter a power plug and we're going to solder on the leads from this 9-volt battery clip for our little project I have over here this is 2.1 millimeters and it just plugs in there and that would power my circuit and I want to power it from a 9 volt battery so I'm going to solder the leads into this connector the first thing I need to do is to unscrew the the barrel so turn that counterclockwise and that will reveal the inside workings now this is the cover for the 2.1 millimeter power jack I need to run the two leads for the battery clip through the end make sur
