do a lot of stuff electronics and i use l e d s a lot and they're fun and they're inexpensive and they teach you nice concepts so we're going to actually do this is this is actually takes a little longer to build and more wires added but it's still given him away for some cause i actually include at the end of life some of my workshops you know arthel been ten weeks together eight weeks together six weeks together doing beck's robotics or some other project  well this one's not bad so just depends it's up to you you know you know you know your students and if you are a student watching this you know what you can you sell and asher parents they are is have stuff available for you  ok so now we're going to put this on twist this on the resist or some member we will twist the three wires together and we're going to put this on the resistor and then we're going to attach it to the battery because the goal here is that we are actually just going to light up the wires in the way i did it we did one at a time right because i just went for use in the alligator clip or the red connector we can do this piece now to a list of that with the other red wire so the alligator clip practically is this piece here and that is just connected to so you have your negative net positive causes just connected to the battery and to do here is actually remove this and i say that you have to put this back through here but this might be easier if you do it this way so let's just take this and twist this and make it into you know solid because it's multiple wires together that stronger wires than the one they built and i think that's really such a neat thing for all actually i'm not going to go on one of my start talk about the brooklyn bridge but it is such engine near marble that i just sometimes love talking about it it's so fun when you read about it and just you know think about when it was built and still out there but that is not what we're doing some get back to where i'm to do it sorry no tension today ok so i just put it through the hole and i bent it and i'm trying to twist it it doesn't give me the best connection i had to say but it is one it's just not the best so i kind because i want to show you this separately so what you want to do this do you want to like this way really you want to put it over here you want to put this through here to do it this is easier this way then you try to figure it out working so it's going to kill that so then when you push this back in here like this camera has a nice connection it can have this plastic piece carol holds that wire in place so it's not too big of a deal but this kind of helps you out so you know the alligator clips or if this is how it looks outside and you want to put it in here i always do this and it's easier so if you have student you work with you know work with them they don't want to hurt themsel way we want to attach an appeal look at where i have a have the negative i have a face in this way right i have the negative here and on my positive here and we can know that by the springs to our right you can tell your positive connection so now let's put this let's put these on we put these on the knee this is actually going to hold if you look at this it's going to hold the battery holder so the first thing i did actually i just took this actually this is interesting i know there is a sad for them i took this and i put this underneath this is like deficit taken and slow thinker we look at this and you look at this they have these pieces here and this is out so we want to do the same thing we want to take this we want to put a popsicle stick just a little bit face and that in the most of it is out or is this way right teach just do in this little simple literacy is flowing through the metal right so it has flown through the metal of this screw and the middle of the wire so i just put this in here very  tightly hopefully we did it correctly if not will figure it out then i go to the next one which is i put a green there so let's just figure out i'm just doing a low off don't i would really if i w put red here but i just notice i put green and i'm going to change it and leave it as green and if it doesn't work with a r why not but we have figured out that's one thing i like about that too you know you know like i said if it something doesn't work the way you think it should work it's always great figuring out why does one that's always a teaching moment those are the best things when something doesn't work because everything works correctly what do you do just like you do the show on the instructional how to do things not teach them some of the basic things they need to know so it's always fun that way and i'm put in the rear in the middle because i made a mistake earlier which is ok i suggest you read for those then green i want to do is have the connection with the wires to that screw so when i put my battery and everything work and hopefully everything will work because i'm actually really up the last couple of minutes if it  little diagram but you know if you have the springs the springs is usually the negative end right right right and these are the thing about this this is this is a little this is a little so we do agree that is open circuit closed my circuit so i'm going to battery right l e d and the next is my red which is a attach it this so now my circuit which has the red l e d s in it is close because i just closed it up so that is so nice so this is again it's up i go e bay it's not that expensive a simple bill it's really
