Here are the activities that each group will be working on today:


If you are new to CoderDojo and new to computer programming this is where you start:

Scratch 1 (Beginner)

This group is for people who want to learn Scratch but have never done it before or who have only done a little bit of Scratch. Make sure you sign in to Scratch so that you can save your work.

1. Racing Game

Click on the link below and follow the instructions in the videos. Try to complete ALL six of the Add-Ons on the final step.

Click here for instructions for the Racing Game project

2. Extra Challenge: Customise the Racing Game

After you have completed all 6 add-ons you will have a basic playable game. However there is lots of room to make it better and more playable. Here is an example of an improved version of the game:

Some additional features that this version has:

  1. Lap Start/Finish line
  2. Lap counter for each player
  3. Half way line (need to cross this for lap to count)
  4. End game with winner after a certain number of laps
  5. Winning time is displayed at end of game
  6. Best time is saved so you can try to beat the best time.
  7. Acceleration and variable speed
  8. Cars slow down when touching the yellow line and slow even more when touching the grass.
  9. Car engine sound effects and background music
  10. Car engine sound effects use built in notes in a loop. The pitch of the note is increased with the speed to make engine sound like it’s going faster.
  11. Cars push each other when they crash.

Scratch 2 (Intermediate & Advanced)

Finish the Snake game you started last week

Snake is a classic computer game where you control a moving snake (usually made with a string of dots or blocks). You score points by eating food but each time you eat the snake grows a bit longer. The game is over if you run into the walls or into the snake’s own body. Click here for an example of the game.

Can you make Snake without any instructions or guidelines?

If you are experienced at Scratch, you can try making the Snake game without any instructions.

Need help to make Snake?

If you need help here are 2 different guides that will help you:

Written Instructions

Already Finished?

When you’ve completed the Snake game, show it to Bruno or one of the other mentors. Make sure it is shared and add it to this studio. Have another member of the group play your game and you play their version. Notice the major differences between your version and their version and share feedback with each other on your different versions of Snake.

If you’re finished with Snake, you can get started on next project – Missile Command

Web Development (HTML, CSS & JavaScript)

Continue with next project

Continue where you left off in the CodeClub HTML/CSS projects or get started on the next project in the series.

Introduction to Robotics

This is a new session with Nathalie. An introduction to robotics using mBot robot kits and a block programming language called mBlock which is similar to Scratch.

Raspberry Pi (with Microcontrollers and other cool stuff)

A collaborative group exploring how computers can interact with the outside world through a range of sensors and controllers. Primarily we’ll be using the Raspberry Pi ( computer in conjunction with Arduinos ( and along the way we’ll learn about Python, C and C++ programming, digital and analogue electronics and about working together.
