simple machines

this is my attempt of making a screw out of connects this is one of the 6 simple machines. screws make stuff hold together. screws can be found in your house and they basically holds your house together

this is a wheel and axel. the wheel and axel makes something move easier and quicker. the wheel and axel is found in cars.

this a wedge. a wedge can split something in half like a axe. but a wedge needs a right sized hole to fit.

the lever enables something to move sometimes using electricity and sometimes not. one of the things that uses a lever is a door handle when the lever is pushed down the door opens.

the inclined plane is just a ramp that leads up to get to another higher point quicker. the inclined plane is can be found in buildings to help people get up the building faster.

this is the pulley the pulley has a little circle and string attached to it  and when one side of the string is pulls the other side lifts up. you can find a pulley in a crane the crane uses the pulley to lift heavy objects.

this is a project we have to do the project is to find a model on a instruction book but the model had to have one of the 6 simple machines the same ones as above. the one I picked is a pickup truck it has to simple machines in it one of them is a lever when the lever is turned the string pulls the string up so it can lift something, the other simple machine is a pulley the pulley works when the lever is turned the string runs across the pulley. I enjoyed doing simple machines a lot and it was also fun to play with wedo 2.0.

ultrasonic sensor

challenge 1



the task was to figure out a way to make the robot sense a wall then stop and you had to make the distance that your sensor was sensing 20 centimetres.


now I will tell you what all the blocks on the program the first one is the start block which makes everything move the next block is the move block I turned the move block to on which means the robot will keep on going forever at the speed 40 until something is sensed. the next block is the ultrasonic sensor block. I started of by changing it to centimetres so I am more familiar with it then I put when something within 20 centimetres is sensed then stop. the first time it I did it didn’t work because my cable wasn’t plugged in properly. this challenge was really simple and it didn’t take a lot of blocks either.

challenge 2


the task was to get the robot to stay in a enclosed space but the robot is not allowed to touch the walls and it has to use the ultrasonic sensor.


now I will explain to you what all the blocks mean. the first block is the start block which makes everything move then move forever till something within 20 centimetres go back 0.8 rotations then turn 215 degrees of the wheel then a loop so it goes on forever this was also very easy.

single colour LED

this was project 1.1 says change the 0 which is the second bubble to 50 but me and Ishaan  did 100 to make it brighter so the program is when space bar pressed LED will turn on and the brightness will go to 100

this task says that you have to figure out how to make it turn off when you press x. the program is when space key pressed LED turn brightness to 100 but when x is pressed LED brightness go to 0 which is off.

the task was to make one turn on then wait 2 seconds then turn the other one on then wait two seconds then turn off both of them off. the program is when space key is pressed one LED brightness goes up to 100 wait to seconds then the other one’s brightness goes to 100 then wait 2 seconds then both of them turn off.

the task was to get two lights but one of them has to have less brightness than the other and also after five seconds it has to turn off. the program is when space key is pressed one of the LED brightness goes to 100 and the other LED turns to 10 which means one is not that bright but the other is really bright.

tri-colour LED

this task says that you have to make a prediction about what is going to happen if you do this program I predicted that it will turn red first because the number is next to the r which I predicted might be red then it might wait because it has a wait block and in it is one second then it might turn blue because it is next to a b then it might wait another second and then it will turn red again then wait another second and then it might go off because there is nothing next to any of the letters that was my prediction and my prediction was right. it also mentions that you have to figure out how to turn it of I figured out that there has to be nothing next to any letters.

the task for 2.2 is to get the tri-colour LED to turn to a different colour every time you press a key but there has to be four different colours and they have to turn on when you press a certain key. the program is when 1 is pressed it will turn to red then when 2 is pressed it will turn to green then when 3 is pressed it will turn to blue then when 4 is pressed it will be a mixed colour between green and blue and at the end we put something that you don’t have to put which is when 5 key is pressed then it will turn off just so we can stop it from wasting the computers battery.

for this task you have to make the LED turn on when the tri-colour LED of and you have to do that ten times In the time of 10 seconds. The program is when space key pressed tri-colour LED has a mixed colour of 10 red 10 green and 80 blue which equals 100 then wait 0.5 seconds after that the tri colour LED turns off but while that is happening the single colour LED turns on then wait another 0.5 seconds then turn the single colour LED off then repeat that 10 times

this was the outputs now all the stuff below is about inputs like sensors.

distance sensor

this task was about trying to make the distance sensor measure the distance. We made it do what the task wanted us to do which was to measure the distance it was simple to do because they showed us the code we just had to plug it in. I am sorry that we couldn’t find the video.

this task was telling us that we had to make a red light turn on and a servo motor to spin when it has an object in 30 centimetre of it and when it has nothing within 30 centimetres of it the light should be off but we couldn’t get the motor to work so we just left it out. the program is when space is pressed if the sensor senses an object within 30 centimetres then tri colour LED will turn to green it is supposed to turn red but we did green but if it doesn’t sense any thing within 30 centimetres then turn the tri colour LED turns to red it wasn’t supposed to turn red it was supposed to turn off but we did red then the last block is a  forever block so the program goes on forever. sorry again that we couldn’t find our video.

the task is to copy that code that they showed us and then they told us that we had to figure out how to make it respond quicker. when we tested the program the motor didn’t move so we tried to fix it but that didn’t work so we didn’t know what to do we tried every thing but still nothing moved we tried changing the wait buttons but that didn’t work so we tried pulling all the wires out and putting them back in but that didn’t work we also tried changing the servo motor numbers but the motor still didn’t move we also tried closing snap and opening it again but that didn’t so we decided we will still show what we tried in our blogs.

lego colour sensor

this is the colour sensor challenge you have get the robot to sense a colour and turn the robot around and make it go back to a different colour like what the video above shows you. The program is move the robot at the speed of 50 then when the robot senses the colour red it moves back 0.5 rotations so I doesn’t touch the paper then 1 wheel turns backwards 0.8 rotations and the other wheel turns forwards 0.8 rotations which means it will turn all the way around and then it will go forward  forever till it reaches green then it stops. we found that the robot didn’t work on the carpet it would get to red then it would turn a little bit around then it would stop. we could only use the 3 white tables because all the others had either green or red but the usually weren’t full because people used the floor.

Lego sensor challenge two



The task was to get your robot to not go off the piece of paper. Also it has to use the switch brick more on that later and the borders of the paper were red so it will never fall off. Me and Haydens robot eventually fell of on those edges that there was no red which is annoying.


The hole program was easy to do and understand the first brick is the start button to make it start. Then thing that I put in that makes a image appear on the bricks screen the one I did is called crazy. This makes eyes appear on the screen but on one eye the eye is looking left on the other the eye it is looking right. The next brick is the move forward on brick which means it will move forever till something is sensed. Then we got the switch brick this brick had to be part of the program the switch brick is brick is like telling it a question. For this I put if green or red is sensed then go back 0.6 rotation’s then turn for 0.6 rotations then keep on going forever.  But if the robot does not sense the colour then it keeps on going forever till colour is sensed. Then finally at the end is a loop so it goes on forever till it falls of. it was annoying at the start because the robot wouldn’t move I didn’t know what was wrong. Then I figured out that you have to put a move block at the start so it would move then sense the colour. Also that day I noticed that it was jolting a lot so then I figure out that you have to put the blocks on coast so it doesn’t stop and then go to the next program but now I made the program to go straight onto the next one without stopping and jolting. after I finished I started to make cool details like the images that project onto the screen which is on the brick. I learnt that you can basically ask the robot a question and how to put cool displays on the screen it was also so much fun at the start trying to figure it out and putting features. I am looking forward to doing the next challenge with the Lego robotics.

challenge three


the task for challenge three was to make the robot follow the black line which was in a oval shape.


the first bit of the program is a image on the screen appears the image is the eyes are nearly closed but not the next block is the sound block it makes the robot say something I made it say ouch these blocks you don’t have to use. The next block is the switch block the switch block is a way of asking the robot a question I have asked the robot if white is sensed then turn 35 degrees at the speed of 10 because you want the robot to stay on the black but if the robot doesn’t sense anything then keep on going at the speed of 10 because that means it has to be on the line and the last block is the loop so it will go forever. I found this challenge really easy.

Me book


1.How did this activity help you to get to know your classmates? This helped me because they told me what they like, don’t like and what they’re interested in.

2.Was it difficult to think of things to draw? It wasn’t that hard because you can draw anything. Like if you did one about your favourite movie you can draw you watching the movie, favourite scene or it on the movie board.

3.Did you discover anything about yourself? I discovered that I like to do and watch stuff with action in it.


Arduino projects

this is the first challenge that we did it was to get the light on which wasn’t that hard.

this one was like the previous one but this one didn’t have a power pack it had Arduino Uno board for its power this was tricky because sometimes it didn’t work so you had to fiddle around with things to see what makes it work.

this was hard because it didn’t work the first few times so we had to fiddle with it and then we replaced the light then it started working.

this was easy because after we did one light it was easier to do the rest because we know how to put it on but first when we did it a few of the light weren’t working so we turned them around then they started to work.

this was really hard because there was 16 wires so we had to be really careful were we put them also for a little while the screen wasn’t fitting on properly but fixed it and we got it to spell hello world.

EV3 robotics

this was hard because if we missed one of the parts we would have to do most of it again. after a while the programing got easier because we became familiar with it but it was hard.

this was hard because if the wheels rotated to much it would go way past the line and you would have to fix it again. one time we were testing it out and it stopped working but then we saw the cable wasn’t put in properly and that fixed it again. it took around four seconds for it to go up.



cardboard shelf

This is about making a cardboard shelf the prototype for the cardboard shelf went really well because it was thin and easier to slot together the slot joins so it only took an hour but lots of the time was trimming it so it would stand up and look cool but after a while it stood up. The thicker cardboard was much harder because the slot joins took a while to make the slot in and you couldn’t use scissors you had to use a stanely knife to cut through the thick cardboard but at the end I was able to finish it.

light up mask

This is a light up mask and this what we did for our second design project that we do at school. It was really cool when the mask lights up after you have done all the work and it looked so cool with all the lights working. Decorating the mask was fun because then you get to design it how every you want. My favourite part was finally getting he lights to work which was a great feeling of excitement and the you got to wear it around everywhere but the hardest part was knowing how to sow the cotton on the lights.
