Raspberry Pi Setup

Once your Raspberry Pi has started up you will

need to login with these details:

Login: pi

Password: raspberry

Now type startx to load the GUI (graphical user

interface).

Open Sonic Pi:

(Start > Programming > Sonic Pi)

Sequencing

A computer works by executing instructions one after another in a specific order (or sequence).

A sequence of instructions is called a program.

Type in this sequence of

instructions and test it.play 60

Notes

Each number represents a different musical note.

Task 1

Write a sequence of instructions that will play this song:

Write down your completed code below:

Shutting Down

You need to make sure you shutdown your

Raspberry Pi properly otherwise you could damage

it.

Exit the GUI:

(Start > Logout)

At the command line type:

sudo halt

Homework 1

Debug this program by highlighting and

annotating the errors:

play 37

pay 49

Write a sequence of instructions that will play 6

notes with a 2 second delay between each one:

Loops

Sometimes we need to repeat the same set

instructions several times. For this we can use a

loop.

Type in this sequence of

instructions and test it.

Change the program so that it

repeats 10 times.

Task 2

Write a sequence of instructions that plays this

song, making use of loops for sets of notes that are

repeated.

Write down your completed code below:

Homework 2

Write a set of instructions that plays 10 notes that

loop 3 times.

Lists

Rather than writing out each note on a separate

line you can use a list.

Type in this instruction and test it.

play_pattern [40,25,45,25]

Now type in this instruction and test it.

play_pattern [40,25,45,25], [1, 1, 1, 1]

What is the difference?

Task 3

Write a program to play this song making use of

lists and loops:

Write down your completed code below:
