Video transcript

so in this video we're going to begin to wire up our motors or using some blue wire again this is just to make the wire stand out so it's easy to see where it goes you can use any color you want it's 22 gauge wire solid core so you're going to want to use the wire strippers because the wire is so short it's hard to grab on to so I'm using the needle nose pliers to make sure that I can pull the insulation off with the wire strippers and of course different wire strippers work in different ways so we're going to loop the wire on both ends and the first one's going to go through the remaining terminal on our single-pole double-throw switch that is closest to that motor and this is of course our needle nose pliers again we're crimping that wire tightly against that terminal just to make sure there's a really solid connection I'm going to take the other side of the wire and we're going to feed it through the terminal on our motor so we've got a little brass tab there with a hole in it I'm going to slide that wire through the brass tab and once we have the wire slit through the breast tab we're going to bend it back and make sure that the brass is in firm cannot contact with that wire so it's important to make sure that those connections are good before we hot glue them together and we did the same thing to the other side just ran the wire stripped it and ran it through the terminal on the motor there and then also the terminal on our single-pole double-throw switch so exact mirror image of what we just did on the previous connection and again it's important that you make sure that that brass tab on the motor is folded over the wire in such a way that it's got a good solid connection if it's just on the edge it may not stay connected so now what we're going to do is we're going to take a look at whether or not our motors are connected correctly and we're going to use our power wire and we're going to strip just a little bit of the power wire off this is from the negative side of the battery and the blue wire actually comes from the positive side so we're going to strip a little that wire off and now what we can do with that wire is we can test to see whether the motors are actually working so we're going to bend the wire over and try and touch it to the the motors there and you can you'll be able to hear the motor spinning yeah and that one worked there and we'll see if it's connected well here yep it works well there too so now we're ready to take our motors and hot glue all the connections together so that the wire stay in place and sometimes what I like to do is bend the wire back up over the connection just to make sure there's it's we're doubly sure that the connection is solid and before hot gluing it because once you get the hot glue on there it's hard to get it off and so it's hard to to fix it if if the connection isn't quite what it should be so again at this point now we're going to hot glue the connections together and make sure that those wires stay in place we've already validated that they are conducting electricity we're also going to put some hot glue on that paper clip that is holding the motors in place so that will that will keep the paper clip in place where again hot glueing over the terminal there so there's a whole lot of hot glue going on at this point in time but it's going to hold our motors in place and it's also going to insulate our our bot you can use the the two bottle caps to hold the bot up so that the motors are off the table surface and that will allow you to basically let the glue dry and keep the motors in the right orientation
