Step 1. Situation analysis (CTc3sc2). Which algorithm can we use to have an instrument make sounds when a sprite (Scratch, for example) touches it? Which code block allows us to add a certain sound to a sprite? How can we create a melody using these sounds? Step 2. Contribute to the program (CTc3sc4). Choose the right algorithm thanks to which the electric guitar will play when it touches Scratch or Vibot. Then, choose the sounds that you like in order to create a melody. Add a fifth instrument and choose the a character that will be able to use this new instrument to make music. Step 4. Modify the program (CTc3sc6). Vibot would also like to play the classic guitar. Change the algorithms to make sure that Vibot can too play the classic guitar. How can we have both Scratch and Vibot play the classic guitar at the same time? Step 5. Use the program Try to create different songs with Scratch and Vibot. If you wish to personalize your band, you can record your own voice and upload it to Scratch. You can use the appropriate algorithms to make it so that your voice is heard when a sprite touches the microphone, which is at the centre of the room.
