For the past two design days I have bean learning how to control and program TELLO drones.
ABOUGHT THE DRONES
- TELLO drones are small and black.
- They have propeller guards and cameras.
- It takes 30 minutes to charge a TELLO drone battery but they go flat in abought 13 minutes.
- There are multiple ways to fly the TELLO drone. these include ‘bricks’ [programming] and controls.
FLYING THE DRONES
Me, Poppy and Addy took turns to fly and film the drone. These are some awesome videos We filmed [all of them are from the TELLO drones perspective].
The TELLO drones controls are pretty simple, there are only eight different buttons.
When the top button in the picture is held the TELLO drone will fly higher, if the bottom button is held the drone fly’s lower. If you hold the left or right button then the drone will turn [left if you hold the left button, right if you hold the right button]
When the top button in the picture is held the TELLO drone will fly forward, if the bottom button is held the drone fly’s backwards. If you hold the left button then the drone will fly left and if you hold the right button then the drone will fly right.
For the past 2 weeks we have bean learning how to program a Lego robot called a EV3. The EV3 robot can avoid objects, follow a line or escape a maze using sensors. There are different types of sensors like the touch sensor [which can tell if it bumps something], The colour sensor [a sensor that can tell what colour something is and make the robot stop once it reaches that colour] and the ultra sonic sensor [the ultra sonic sensor can tell how close it is to a object and make the robot stop if it is going to crash].
ME AND SASKIA’S PROGRAMS
Using these sensors, my partner Saskia and I have been able to create many programs, not all of the programs have worked.
PROGRAMS THAT HAVE WORKED
Colour race is the first program that Saskia and I made that uses the colour sensor. This is the code for colour race.
The first brick in the code is a start brick. Putting this brick at the start of your code means that the brick that comes after it will be used at the start of your program. In this code the brick that comes after the start brick is a move brick, this block can move any two motors. In this code the two motors that move are the motors plugged into ports B and C [the wheel motors]. We have set the move brick to on mode so the motors will keep on going until something signals that it needs to stop this is what the third block is for. The third brick is a wait brick set to the mode colour sensor, white, this means that the EV3 robot will wait until the colour sensor sees the colour white before continuing the code. The last brick in the code is another move brick but instead of setting this brick to on mode Saskia and I have set it to off mode this means that the motors B and C will stop.
OTHER PROGRAMS THAT WORK
- baceball challenge part one
- face change
PROGRAMS THAT DON’T WORK YET
For the first five weeks of term two we have bean learning how to code microbits.
Microbit coding is a bit like scratch except more complicated and instead of coding sprites you code red lights to flash on and off. This is a example of a code.
In this code there are two types of brick, four blue bricks and a purple brick. There is a lot of different types of bricks. These are some of the most commonly used bricks.
- Basic [blue] bricks, These bricks are simple and easy to under stand. some examples of basic bricks are ‘On start’ [when this brick is attached to a group of bricks these bricks will ocker at the start of the program] and ‘show leds’ [whichever leds are selected will appear on the microbit]
- Input [purple] bricks, These bricks say what to do when a certen thing happens. These are bricks like ‘when button A pressed’ [when the A button is presed do…….] and ‘on shake’ [when the microbit is shaken do…….]
- Music [orange] bricks, you can use these bricks to play music.
I have nine projects different projects:
- duel……….This project is my favourite project, you press the buttons to use spells like Expeliaranus.
- quitege……….i haven’t finished this project yet but once it’s finished you will be able to doge obstetrical’s to get the the quaffle to hoop.
- tug of led……….this is like tug of war but with a red dot instead of a rope.
- dance……….you press the buttons to make the character dance.
- emojis……….when you press the buttons different emojis appear on the microbit.
- micro chat……….using this project me and Addy can send messages to each other.
- rock, paper, scissors……….using this project me and Addy can play rock paper scissors on our microbits.
- Archie’s tug of led……….this is a project i helped my brother make.
- flashing fish……….this was very easy, a fish picture flashes on the screen.
Next i am going to make a Accio Battle and a cello game.
Octopus Fact Clicker
Octopuses are strange but fasinating creachers, this is why i have chosen to make my makey makey project about them.
My project will be a….. [drum roll] OCTOPUS FACT CLICKER!!!!!!!!!!!!!!!
I will have a picture of a octopus with foil covering parts of it. You will be able to click on the foil parts of the octopus it will say some thing like “if a octopus louses a arm it will just grow back” or “male octopus have a whole arm just for making baby’s!!!!!” 😱😱😱 Shoking but true.
How it works……
Behind the paper there will be a pice of foil, the pice of foil will have a wire leading to the makey maakey atteched to it.
I hope you enjoy learning about one of the worlds weirdest creachers!
In the makey makey bongo progect we hade to use our makey makeys to play a online bongo set here is the link: https://apps.makeymakey.com/bongos/.
I found this project quite easy because we only had to plug in 2 bananas, the left arrow banana and the space bar banana. When you click the left arrow banana [or what ever it is] it will make the lower sound. If you click the space banana I will make a higher sound. Both noises sound like a bongo drum.
One of the makey makey challenges was the piano challenge. We had to use our makey makeys to make an onine piano. Here is the link:https://apps.makeymakey.com/piano/.
The piano challenge was similar to the bongo challenge except a bit harder. As well as plugging in the left arrow and space bar banana we also had to plug in up arrow, down arrow, right arrow and click. The left arrow made the lowest noise and click made the highest noise. All of the noises sound like a piano.
What is electricity??????
Electricity is an energy that flows through things like computers, helping them work. Electricity is in lots of things here are some examples:
- digital clocks
- air conditioning
- fish tank filters
- anything that plugs into a power point
In design we have bean using Makey Makeys. A makey makey is a board you clip wires on to the board and clip the other end onto some thing like a banana, when you touch the banana it should work like a computer key.
If it does not work it is probably because of one of these reasons:
- you are not holding the earth wire
- the earth wire is not clipped to the makey makey board
- the wire is not attached to the banana
- the other end of the wire that is attad to the banana is not attached to the mackey makey board
- the matirial you chose is not one of the working material. Here are some working materials:
- play dough
Here are some materials that do not work:
- card board
- china [plates and bowls not the contry!!!!!]
<–Banana key board!!!!!
In Scratch we created a project called Build-a Band. We had to make our sprites play music.
This is a picture of my code. The green blocks are a special add on called music. The music blocks play notes. In my Build-a-Band I have 4 instruments: cello, piano, drums and a microphone.
Scratch is a coding program where you can create videos, games, music and more!! It is fun and educational.
Here are some things you should know:
Code: A set of instructions
Sprite: A character
Costume: What your sprite looks like
Block: A single instruction, you put blocks together
In scratch we have been given many challenges this includes the build a band challenge.
We had to make our sprites look and sound like they were playing music.
Timing was the hardest part!!!!
