Line Sensor Challenge

In this challenge you have to program your robot to go on a black line, in a circle, but if it goes off the black line onto the white, it should sense that, and try to find the black again.

In this video below, Bobby is following the line. YAY!! That means we are ready for Robo cup, with Lexie and Grace. If he can do this we can possibly do Robo Cup. I think this project is testing to see if all colour Sensors are the same, which they aren’t. Lots of people think this Challenge is hard, of course its going to be hard its Challenge 6. I’m very glad that we finished this project earlier, because last time we got the Switch Colour Sensor project in the morning it was due! And we have already finished this one, and we only received it yesterday. The hardest part of this challenge was when we first got it, he would just spin around on the line instead of actually following it.

Robo Cup: Lexie, Grace and I are entering as a group in RoboRobo Cup. We will be using Monty, Lexie’s Robot. If Monty goes of the line of the course, as in do a circle and then come back to the line, we lose 10 points.

 Here is the program for this video. His expression is happy when he is on the line, but when he goes off the line, he has a sick expression because he s stirring back onto the line.

Colour Sensor Switch

challange cs word doc-1wel1pj      Challenge 5:

In this challenge you have to make your robot move to 2 or less colours. For example start in the middle move forward sense red, turn around go to red again on opposite side, turn around, go forward turn right sense blue, turn around, and then, move to blue again on opposite side, sense it and stop.

Day 2: For some reason we still cant get our robot to work [ Bobby ] So hopefully we can get some help from others that have done it before.

It works!! After all this time it works! HOW? Well after to much times redoing this, I decided to get help, turns out I was playing the demo instead, it was Challenge Colour sensor, and its called transporting to colour. That was the problem all along!! We feel more satisfied now that we have finished this project. I will now use my knowledge for the next challenge. I am so happy. It was just a matter of fiddling with what the program was called. To me this is a HUGE achievement! It was completely fine!!

Humming Bird

This is the TRI-COLOUR LED. And when I press the space bar it goes on to red for 1 second, then it goes onto blue for one second, and with the third one we realised that it had 100 red and 100 blue, and blue and red make a purple kind of colour. So if you fiddle with red and blue you can get all types of purples and pinks. And then t turns off, because their is no brightness in any of the lights.

This is the Humming Bird. Here we have put this LED into Humming Bird, and when you press the space bar it should flash, but for some reason it doesn’t work yet. But hopefully we can fiddle with the cords and then it should work.

Second attempt on hummingbird LED:

This time when you press x it flashes, press it again it flashes. With the one we couldn’t do before, now when we press the space bar it shines for 3 seconds. Which is exercise 1. 2.

In this exercise Bronte and I couldn’t figure out what was wrong, but then we realised that it said ” Hummingbird LED 1, and that my computer could only communicate with the orange LED. Now in the one below it says Hummingbird LED 2, and that’s the green one. Or you can press x, the orange one will turn on wait 2 seconds, and then the green one comes on and they stay on together.

Colour Sensors

Colour Sensor Program 

Challenge 4:

This is Bobby and he is doing a challenge that involves using this colour sensor. When he sees the red, 5, he turns around or he could stop. The light that is shining on the table is the sensor, when he sees the colour we programmed him to see, the sensor alert runs through the cords to the block [ Bobby ]. The programming is kind of different to how we normally do it. The first block is the play button, 1. And the second block is the steering,  direction and speed, 2, 3. On the orange block, it has the small red square, and that’s the colour Bobby stops at when he senses it, 5. I think this project was a great experience to program a robot to stop at a colour, and now I should be ready for challenge 5.

Arduino Reflection

This is the Arduino project that  Lexie, Bronte and I have been doing. We have had different types of projects for this project, to help us understand more about this machine, not different from this but smaller challenges such as the LED light staying on all the time, the blinking one and the one with the button which is this one above. The second photo, well…. it didn’t work  properly, all the wires were in the right spot, but… hopefully next time in term 3 we might try it but, otherwise we might try one new project.

We needed the Bread board, the Arduino board, 330 resisters also other numbered resisters that we didn’t use, the cord to plug into the computer to power the Arduino apart from the one where you uploaded it and pressed the button, LED lights, the small colourful cords that travel the electricity around the bread board along with the resisters and buttons. I think my group and I really enjoyed experimenting, and finding out ways to send electricity so it wouldn’t blow the LED globe. These past few lessons have been really educational because you learn all about different electricity components, and I never really have known much about all electricity and how it travels until now and when we did the Circuit Masks, but now I know lots about electricity and how it travels.

Lego Robotics EV3

Move Straight & Turn Challenges-s80b5w

Move Straight & Turn Challenges-s80b5w

This is the start of building the EV3[ Robotics]. This is only half of the EV3. So far one side is finished. Me and Grace have just started doing the other side. I hope that next time we can do more. The really annoying thing was when you got the wrong pieces! Today we finished the other side, only to find I had done it the same as the other side, so we had to de-construct one side. But the good news is we have connected both sides. Hopefully we can accomplish it tomorrow. Because without one piece the robot won’t do a certain thing.

The nearly done Robot is the first photo, we just have to plug in all the wires and then we can start programing it. So far in this program, its been great fun building and connecting all these new parts, this Lego was more challenging as normal Lego. It was really annoying when we had to de-construct it twice!! For some reason we  firstly  couldn’t do the diamond shape but then we realised that you had to repeat the program, move straight then turn right 4 times and it worked! I also noticed that the white wedge in one rotation of the wheel the wedge would spin around once, which is a whole rotation of the wheel. I guess  that’s what design is all about!

Me Book Reflection

This is my Me Book.


  1. How did this activity help you to get to know your classmates?
  2. Was it difficult to think of things to draw?

Did you discover anything about yourself?

This activity helped me learn more about other people I don’t usually play or talk to, but the people I usually play with I already knew more about them but it was fun to see their lovely illustrations. It wasn’t really difficult to think of things to draw because in my Me Book I had a page about how I love to draw, which is above, as you can see it says it helps me express my feelings and emotions, as well as working on my drawing skills. So that helped a lot when doing this project. I discovered that I LOVE PIZZA! Usually Pizza is 1 of my favourite foods but now I’ve discovered its my number 1 favourite food! I think this project really helped everyone, because now lots of new people know lots about everyone! I loved doing this project, it was very satisfying showing stuff about me and looking at all the good work that everyone had put into their Me Book🤗😊!!




My Circuit mask

The past few lessons we made these electronic masks that had a circuit, positive and negative energy.

I thought it was my favourite, because the electricity was in side the string of the sewing. I also learnt that if you don’t get the wires right in the positive and negative it won’t work, why? because the electricity is in the wrong wire, it needs to travel through the wire, and gets the energy from the battery. That’s why its called a circuit, its a circuit of electricity travelling. I loved this project, I think lots of people did GREAT!!
