so now in this video i thought we'd take a quick look at a breadboard power supply right here so there's uh some variations but for the most part they work the same so we will zoom back a little bit it has pins here and we can just plug it right into a breadboard as long as the pins are aligned properly there we go it shouldn't be too bad but sometimes you may have to fiddle with it a little bit before it will fit there is a little plus on the row where the red line is there's a little minus on the row where the blue line is on both sides as you can see there so that's how you will know the polarity if your breadboard does not have these lines for some reason of course you need to power the power supply and it just uses a typical nine volt barrel jack right there and this is the only part that you power it in right here and you don't want to go above nine volts right there and now you c
