Video transcript

so in this video we're gonna install the switch you see in the lower center of the screen that's the on/off switch for Bitsey and the first thing we need to do is just take the switch and push it through the hole that we drilled out and marked in a previous video so we're gonna push the switch through and the holes just about the same size as the threads so it's a pretty tight fit takes a little wiggling to get the switch through there so then what we're gonna do is we will put the the nut on the switch that will hold it in place so we're just using our screwdriver to slide it over the end of the switch there and we'll hand tighten that it takes a little bit of doing we got to push the switch through from the underside and then and then just turn it a little bit once we've got the the nut lined up and on the shaft of the switch we can we can tighten down the rest of the way with our it's look it's taking a little bit of time there and you'll probably have a similar experience it's it's tricky to get that on especially with all the other parts that are around the bot we're really close to the edge but there we go we finally got it ok so when you take your needlenose pliers you can tighten it down the rest of the way alright so now what we're gonna do is we're going to solder our wires to the switch and we have the wire coming from the battery this is the positive wire coming from the battery and we're going to cut it to the right length and then we're going to strip the end of it and then we're going to bend it in a u-shape and that you shape we can wrap around the contact on our switch so we want to try and give it get it in in almost a perfect U and once we have it in that shape we can put it around the contact and once it's around the contact we can use our needle nose pliers to crimp it in place and make sure that's nice and tight against that connection there and then what we're going to do is once the wire is firmly in place we'll get our soldering iron and we'll solder the wire to the post in the switch so what the switch does is basically just stops the flow of electricity by disconnecting the wires okay so we've soldered that one on and we'll solder another wire on to the other side of the switch the other side the wire that's on the other side we'll go directly to our motor controller and that's where the power is going to come from at the bet the power from our batteries is going to go to the motor controller and the switch will allow us to break that circuit and and shut the bitsy bot off okay so we've routed our power wires from underneath up through the holes and over to the motor controller so now we're just stripping the wire clean there this is our positive 12-volt wire and it's going to go to the to the pin in our terminal block on the far right side the terminal block in the center there and we're going to just we've already loosened the screws and we're gonna feed the the wire into the pin and then we'll tighten the screw down on it to make sure that it doesn't come out so that is the wire that came directly from our switch and there's our tightening down the terminal block there the screw and the terminal block so we have our negative wire which has come directly from the battery and we are going to run that to the screw that is on the far left hand side of the terminal block that is our ground wire and so we've stripped the edge off the end off of that wire and we've just push it in underneath the screw there in the left side of the terminal block and now we're going to take our 22 gauge wire and we're gonna run 22 gauge wire into the ground this will allow us to ground other components on the board using the the motor controller as our sort of junction box so we're going to push our 22 gauge wire into the same terminal block as our 18 gauge wire from our battery and it's not a lot of room in there but we're gonna try and slide it in sometimes you have to move one of the wires out of the way to get the other one in and our course our needle nose pliers can help push the the wires into place and then we'll take our our screwdriver again and tighten down that terminal block to make sure the battery the wires won't come out and then we're going to take a 22 gauge wire and run it to the center terminal block center of that terminal block which is going to provide us 5 volt 5 volts out that we can use to power our digital camera and our Arduino and other components on our board so we'll wire that to our breadboard in the upcoming videos
