but we're gonna wire up our lt98 motor controller we're gonna position it right on top of the camera where the batteries would normally go so in order to get started we've begun taping the area that we're going to attach the lt98 motor controller to and the tape serves a couple purposes it protects the board from the sharp leads on the bottom of our lt98 and it also allows us to remove the l-29 t8 should we need to later because we're going to hot glue it down so the Arduino we're gonna remove the Arduino because it is kind of in the way we need to route wires and it's a lot easier to route those wires when it's not there so we're taping down the control wires for our camera those are the shutter and power wires and now we're routing the wires from our switch that is the on/off switch up to where they'll connect with the motor controller so we're going to go underneath the camera to do that and we're just using our needle nose pliers and then this is the switch from the the battery are the wire from the battery I should say and we're going to pull that through as well and you kind of just want to make sure that you are careful in that you don't knock any of the components on the bottom of the camera loose when you when you route those wires up like that but if you go underneath the camera it makes it makes it look a tidier and it's a little little more straightforward so now we're going to tape over the leads on our capacitor that's on our camera there we realized that the l-29 t8 has some some leads underneath that could potentially touch it and cause a short so we want to make sure that doesn't happen we're just covering it over with electrical tape and double checking the position of the l-29 t8 and then what we're gonna do is we're going to take our hot glue and squirt out about 3/4 of an inch in diameter blob of hot glue and we'll let it sit there for just a few seconds about 10 or 15 seconds and then I'll allow it to cool just a little bit and when it cools it gets a little stiffer so it provides a little more of a cushion between the camera and the bottom of the l-29 t8 once we install the lt98 so we'll position the l-29 t8 where it needs to go and the motor controller there and we'll let it sit there for just a second and we'll come back to it before we wire it'll take about two minutes for the hot glue to fully cure and Harden so now it's it's definitely hardened inning and in place and so the lt98 is secure so now what we're gonna do is we're stripping the wires that are going to go to our motors those are the wires that have come up from our motors I should say and once we've got those strips we're just going to connect them to the motor block terminals so you can see we're just pushing the wire in there and then we'll tighten the the screw and the motor block terminal down and that's how we we wire our our motors so the each motor has two wires and both of those wires go to each one of those blocks so each block is for one motor the so now we're connecting the the last wire for the motor on the other side and we just tighten that down so now we're going to connect the wires that are going to come from our ad we know and tell our motor controller which speed and direction each motor should go so there are different markings on each of the the input pin outs and you can see that the first one there says l1 and then there's an l2 right next to it l1 and two are going to be individual wires that run back to the Arduino L three and four are also going to be individual wires that run back to the Arduino now there's another pin out right next to the terminal block that's a one and two and we're going to connect a 1 and 2 to e 3 and 4 so the way we'll do that is we have a short wire we stripped extra of the short wire off and we're just wrapping that around another wire that we've stripped so that we can connect the two so we're going to create what's called a jumper and it's going to connect II 1 2 with III 4 so now what we're doing is we're just soldering the the jumper together and in order to do this we're heating the the part that's wound around the the 1 wire that's wound around the other and as those wires get hot enough they'll melt the solder and the solder will actually wick in around the joints you can see it go there and that uh that'll make a nice strong connection that we don't have to worry about coming apart now we're just taking some heat-shrink tubing that we've cut and using our heat gun to melt that or to soften that tubing and shrink it around our connection and that will prevent any shorts in the future so if stray wire touches that it won't won't short out and we're just waiting for the heat shrink cooling to dry and we're trimming off just a little of the excess and we'll take our jumper and connect it to e1 e2 e3 e4 which are the the two remaining pin outs and we discovered that it's just a little long so we're gonna trim off the excess and then we're going to try and strip the the wire and take just a little bit of the the insulation off so that we can put it in the pin out and it's tough to get the wire insulation off when it's thatthat short so we we used our nipper pliers to finish that off so we're gonna make our connections there between II 1 e2 and e3 e4 again taking just a little bit of extra wire off it's it's not always easy to know exactly how much you need but we don't want a whole lot of excess wire sticking up because it may not may be able to get knocked out that way so so we're gonna route our our wires down you should have a total of 5 wires coming out of the motor controller and we're gonna route those down and then try and put them together in a really neat fashion before we do that we'll trim off the excess from this wire I'm gonna put them together just lining them up so they're parallel to one another and so none of the wires are sitting on top of each other so they're all just sort of lined up in a nice neat row like lanes and highway and then we're gonna tape them down with our electrical tape and that'll help to keep them in place and keep them ordered and again we want about the wires to stick up past the side of the plastic housing about an inch and that will give us some access if we need it for connecting to the Arduino
