Week 6 2018 Explorers – Greeting Card

Hi everyone,

Good to see everyone after our unplanned extended break, but it was nice to see some snow too!

This week we did a Greeting Card, I did a birthday card but some of you did a Mothers Day, I’m sure all your  Moms loved them.

I have uploaded the finished card up to the scratch website. You will find the log in details in the notes below.

Enjoy the break!



Week 5 2018 Explorers – How fast can you type?

Hi everyone,

Thank you all for coming on Saturday. I hope you liked the short video of the SpaceX Falcon Heavy Test Launch and the Intel Light Drones from the opening Ceremony of the Winter Olympics.

This week we did a new game, How fast can you Type? Last week we used Sprites as backgrounds and this week we used Backgrounds as Sprites. Just to mix it up!

We used a variable as our Timer, our first time doing this, don’t forget if you want the time to start when you press the first letter rather than when the green flag is clicked then you are going to have to add another broadcast.

We are off for the next two weeks, to cover the school mid term break and also as Confirmation for all the Athenry Schools takes place on the 24th of February and there will be many families attending this from Coderdojo Athenry. Best wishes to any of our Ninjas and families who are being confirmed.

Hope you all have a great break and hope to see you all back on the 3rd of March

Week 4 – 2018 Explorers – Scrolling Backgrounds

Hi everyone,

Thank you all for coming again on Saturday and welcome to our new people!
This week we looked at some of the elements we will use in A Mario game we will make in a couple of weeks time.  We will use scrolling of objects in the background to achieve movement rather than making the Sprite itself move as we would normally do.
It can be a difficult concept to grasp for the younger ones, but we will go through it again before we make the Mario game.

Firstly we select our Sprite and we decided we would only move left and right.

We then had to create some Backgrounds. NOTE: EACH BACKGROUND IS A SPRITE. You do not create it as you normally would.

I have put the game on the Scratch Website http://www.scratch.mit.edu. Login with the User name and Password in the Notes Below.

Here are this weeks notes in PDF CDA-S7-Week 4-Scrolling.PDF

See you all on Saturday, we will do a new game that I think you will all like and maybe a little competitive!!!


Explorers – Week 3 2018- Maths Game

Another great week, a lot of work was done in the Explorers room. Hope you all had fun making our Maths game!

CDA-S5-Challenge_10-Maths game-how to

A player picks a level of difficulty and the computer chooses 2 random numbers to add (subtract or multiply- whichever you choose!) together and show the numbers to the player. Fr this we needed 2 SPRITES and 4 VARIABLES called SCORE, LEVEL, NUMBER1 and NUMBER2 as well as 2 BACKDROPS. CDA-S5-Challenge_10-Maths game-ask questions1CDA-S5-Challenge_10-Maths game-ask questions

The player then has to enter an answer to the equation and the computer tells them whether they are wrong or right. CDA-S5-Challenge_10-Maths game-decisions alternative end

We repeated the ask/answer questions 5 or 10 times. Can you figure out where the REPEAT loop fits?

We also had a second sprite who reacted positively to correct answers BROADCAST and negatively to wrong answers BROADCAST. You can use whatever sprites you like and change their look whatever way you like. One coder added a puppy as their second and had him bark whenever an answer was correct. CDA-S5-Challenge_10-Maths game-sprite 2

After all the questions were asked we had the 1st Sprite SAY – Game Over! and BROADCAST Game over so that the backdrop changed and music played. There are two ways to change the backdrop- see below!CDA-S5-Challenge_10-Maths game-alt backdrop CDA-S5-Challenge_10-Maths game-backdropHere are this weeks notes in PDF CDA-S7-Week_3_18-MathsGame.pdf

Also I have uploaded the finished game to the www.Scratch.mit.edu website, just use the login details in the notes.

See you next week



Week 2, Explorers – Pen Commands

Hello Everyone,

A special welcome to all our new members that came to us this week, I hope you enjoyed yourself and hope to see you back again soon.

Thank you all for coming again this week. This week we looked at pen commands, we have not done this before in the Explorers group so it was new for everyone.


We also created some variables which we set as sliders which again is something we had not done before with this group.

And lastly we added buttons to our game. We added two separate buttons, a Start and Stop.











Here are the full Pdf version of my notes from this weeks session. CDA-S7-Challenge-Pen Command.pdf


Week 1 2018 Explorers – Breakout Game

Hi everyone,

Thanks to everyone who came yesterday and special welcome to our new people. Thank you all for your patience with the projector!

This week we did a game based on an old game called Breakout.

The object of the game is to try and get rid of all the blocks by bouncing a ball into them using a bat of some type. You all had your own versions of what you wanted the game to look that and that’s brilliant, your imagination is way better than mine.

The first thing we did was design your bat and write some code to control it. We decided that the mouse should control the movement and that the movement should be only from left to right and vice versa.

The rest of the code and notes for the game can be found here in PDF CDA-S7-Week_01_18-Breakout.pdf

I have also uploaded the finished game to the Scratch Website if anybody wants to take a look at it or for anyone that wasn’t there on Saturday. I will go through  it at the beginning of next weeks session if anyone has any questions.

You will find the login details for our account on the Scratch website in the notes above.


See you all next week and have a great week.



Explorers Week 8 – Making a Start on a Paint Program

Hi everybody,

No notes this week, I will wait until we complete the game this Saturday.

Hope you all enjoyed the visit from Medtronic, we really appreciate the volunteers coming out to see us and showing us all the really interesting and exciting things they do….and the lollipops were lovely too.

See you all next week and we will complete our Painting program



Week 7 2017 – Explorers – Piano

Hello everyone,

Thank you all for coming again this week and I hope you enjoyed the Halloween break.

This week we did a simple Piano.


We only had to draw two keys, and then could duplicate these and change the names. The same applied to the code. The code is the same for each key apart from one small change so the note is the appropriate for the key.

REMEMBER! You need to make four changes each time you duplicate:

Change the name of the spite to the next Note

Change the name of the TWO costumes

Change the NOTE played




Here are notes from this week in PDF CDA-S6-Week_07-Piano.pdf


Explorers – Week 6 – Halloween Scene

Hi everyone,

Hope you enjoyed this weeks session and remember we are off for the mid-term and so our next session is on the 11th of November.

To get ready for the spooky season we created a Halloween Scene, lots of scary sounds and switching of costumes to create the effect of movement.

I chose a Witch with a wolf howl but I saw lots of great ideas as I was going around the room. Some had Ghouls, others Vampires, its was all pretty scary.

We also learnt a nice trick for giving the allusion of movement. We had a bat change both its size and Costume and it worked very well to give the effect of the bat flying towards us with the moon behind it.

Here are the notes in PDF from this weeks sessions CDA-S6-Week_06-Halloween

Also if you want the completed Scratch Code you can download it by going on to the Scratch.mit.edu website login to the CoderDojo Account (details are in the notes) and search for CDA_Martha_Week06.

Hope you have a great Halloween, be safe when you are out Trick or Treating but have lots of Fun!!



Explorers – Week 5 – Guessing Game

Hi everyone,

Well! didn’t we have a very studious bunch of Ninjas last week, all very focused on our new game. Last Saturday we did a slightly different game to usual., There was no movement, no sensing when something happened. It was a Maths Game, a guessing game where the computer picks a random number and we had to guess the number.

We had to first make sure that a random number was picked using an Operator. Previously we have used a Variable to store a Score or Lives, but this time it was storing the random number and our guesses. Leaving them on screen as we were testing allowed us to understand more about the variable and what it does…it also made the testing a little easier.

Depending how any guesses we were given we repeated our code that number of times. As well as having to make decisions, i.e If_then, we also had to do a comparison before making the decision, to determine whether the guess was correct, too low or too high.


I hope you all enjoyed the difference this week and we are going try something else different next week. We  (You)  are going to create a Animated Halloween Scene. Get your Thinking Hats On!
