good morning everyone I'm seen this man so much Sunny face in a while so I had to pull on my college week my NAU shirt for Northern Arizona University and Sport not today because I'm already my nephew was quarterback for you last week he was signed by the New York Giants quarterback or one of the quarterbacks so I wish him the best of luck taste quickest and thank you for giving me the opportunity to be the quarterback I am going to be doing helping you with the next one is more advanced pieces are going to use some different items that we haven't used before until 1 a.m. are you get somebody to help before you start on any of the levels this one in particular is going to use a counter counter to use all the time in programming help keep track of the number of activities that something is going on so counter becomes a very useful way to make sure your robot does exactly what it's supposed to do the correct number of times so we're going to use a counter here and it's going to be on the grid map that has the numbers so the number grid and it's going to mark off all of the on the grid so it has to be able to find his way around the grid as well as Mark at the same time in a logical Manner and also finish without crashing at the end so imma take you right here here's the screen for the code for right now we're going to have to go all the way around and we danced a few things out first of all you know what's going to be what's our plan of attack here so you'll see little ones to her asking you to sequence and so it's best we score these often sequence it's going to capresso I want to create a series of loops in the situation that are going to help me to complete this challenge you'll see that if I was to drive forward here turn and come back to hear that would be considered one live so I go from 1 to 10 I'm from 20 to 11 and I'm now back almost exactly the same spot except the one I've moved forward one square that would be one look answer to complete the the square I would have to do that full five times while I shuffle my way down the square at the same time okay so we're a couple things to start here we're going to go down then we're going to go to our variables and we're going to create a variable or cell phone that variable is going to be our counter and remember you don't have to call this counter you can call it number counter whatever you would like as long as it's appropriate and so now I have a variable call counter this is going to be useful to me I want to be able to set the variable and you'll see right here I can say stuff the counter to zero counter is my variable looking to help me to do that now I could have, to get used to being alone I can say counter keeps track of Publix okay that's going to keep talking about the great Cruiser pseudocode so it's not going to actually read anything here okay so how many times would I have to complete this Loop well I'm going to have to 5 * I'm going to have to use the repeat block so if I block I can drop that in and I can tell it something 5 * 400 repeat something 5 times so what's it going to do well it's going to I have turn right 90 degrees and then I have to drive 12 hours all I said was based on our previous pieces is going to be 200 / Square 1800 rifle then it's going to turn last read the ten number here it's going to drive forward to 20 the number for me that's going to be a block 200 then it's going to have to turn right again and then it's going to drive back 1800 so it if I run this we'll see what happens here are there ghosts turned fright drives down Kearns that's the wrong way so it looks so that's a left turn right there I would that try that again so we're going to drive forward turn right and now coming back now this is where interesting, because right here it's going to just start driving because it's now on the wrong piece so that's not going to work for me right there so at this point I know this is correct this is long Loop right now okay but I'm different this repeat so now I need to tell it that it needs to do once it finishes this look and needs to do something else okay so that's going to mean that I have so on the slide down find my if statement all right I know please this is going within the repeat. So it's going to go down completely and then I want to give it to command so the first thing is this is that I need to let it know that if the counter changes then eats going to when we get to this point that the number for peace has to be reduced by one so it has to be done by 4 so I'm going to go and find my greater than less than sign here and I'm going to say need to do this naked Boston pot okay now that's a good lesson 5 and I got to have that beautycounter right so as long as the counter is less than 5 set timer loose we have what I want to do well I would like it to turn right 90° and drive forward 200 so now it's going to come back around turn around drive forward 200 instantly starting back into the loop again cuz going to go through this code check to make sure husband five laps do this decode and repeat and repeat and repeat the one issue that we have is that obviously this number is not going to decrease so we have to make that number decreased can you do that we need to come up with a block that will help us do that and there is under your variables a change so inside the repeat we're going to say change counter by 1 and that's going to decrease the number all times it's going to repeat so it's going to say that's now been decreased and it will remember 5 4 3 2 1 so now when I hit the start button we could turn and off we go so it's going through that first portion of the code for its driving across can I make a left turn they make the right turn then come back the office attraction and then it's going to go into it's Damon it's going to verify that it's got the counters less than five which it is and it's going to keep rolling along it's making the correct term you can see now it's heading backwards and it's looking each time as it works its way across remember each time it makes the turn at the far end of year the counter is being lowered by one I'm cutting off I was going to return Anthony Kennedy and the code. So it's verified that the counter has run down all the way to zero and it now brings the robots are going to stop and that is how you would make it to the number for level two and three different patterns but the problem is supposed to be the same in terms of getting into this thing and making a loop so that should be helpful to you and remember to make the New York Giants score out of 50
