You will need:

Parts included in class kit

▪ 1 Crumble controller

▪ 1 micro-USB cable

▪ 1 sheet of corrugated plastic

▪ 4 crocodile leads

▪ 1 motor

▪ 1 motor mount

▪ 1 bulb holder

▪ 1 bulb

▪ 1 LED

And either (older kits):

▪ 1 battery holder 2xAA

▪ 1 battery snap

Or (newer kits):

▪ 1 switched battery holder 3xAA

Other parts, tools and consumables

▪ 1 computer with internet connection (Netbook

computers will work, but not Chromebooks)

▪ Pencil

▪ Ruler

▪ Large scissors

▪ Double sided sticky tape

▪ Low melt glue gun

▪ Pencil sharpener

▪ Sandpaper

▪ AA cells – either 2 for the 2xAA battery

holder or 3 for the 3xAA battery holder (use

zinc cells, not alkaline or re-chargeable)

Step 1

Screw the bulb into the bulb holder. Fit the motor into the

motor mount - push it in from the end, not from above, to

avoid snapping the motor mount. Use the ruler and pencil to

draw a square 12.5cm x 12.5cm on the corrugated plastic

sheet, then cut it out with the large scissors to make the base.

Step 2

Draw and cut out a rectangle of corrugated plastic sheet 1.2cm x 5cm.

Stick a strip of double-sided tape onto one side of the rectangle,

remove the plastic backing and stick the rectangle to the Crumble

controller as shown. Make sure you attach the rectangle to the side of

the Crumble without components on. The purpose of the rectangle is

to allow height for the crocodile clips to attach to the Crumble

contacts.

Step 3

Stick the other side of the plastic rectangle to the base in the

position shown. Make sure you leave space on the base for the

battery holder. Plug one end of the micro-USB cable into the socket

on the Crumble controller (first look carefully at the plug and socket

to make sure they are the same way up). Plug the other end into a

USB port on your computer.

Step 4

Set up a destination folder called ‘Crumble’ on your computer where you want to install the

software, e.g. on your Desktop. Download the Crumble software onto your computer from here:

https://redfernelectronics.co.uk/crumble/. Double click on the downloaded file and run the set-up

wizard. Click ‘Next’ then when asked where to install the Crumble software click ‘Change…’ and

choose the destination folder you set up earlier. Navigate to your destination folder and double

click on ‘crumble’. The following window should appear.

Leave space here for battery holder

Step 5

Construct a program to run the motor at 50% power for

5 seconds as follows. Drag commands from the list on

the left hand side of the screen and drop them into the

blank space on the right. Each command needs to

attach to the one above it. First drag ‘program start’

across. Then attach ‘motor 1 STOP’ to it. Click on

‘STOP’ and it will change to ‘FORWARD at 75%’. Click

on the ‘75’ and type in ‘50’. Attach ‘wait 1 seconds’,

then click on the ‘1’ and type in ‘5’. Attach ‘motor 1

STOP’ again to finish.

Step 6

Click on the green arrow (top left of the screen) to run your

program. Motor 1 LED on the Crumble should glow red for

5 seconds and then switch off. Save your program in the

Crumble folder – call it ‘Run motor’.

Step 7

If you have the 2xAA battery holder, tie the battery

snap wires in a reef knot as shown, so the metal ends

point away from each other and don’t accidentally

short circuit your battery by touching. Make a label for

your battery holder saying ‘Use ZINC cells not

alkaline’ and stick it on.

Step 8

Fit the cells into the battery holder (the right

way round). If you have the 2xAA battery

holder, stick it to the base. If you have the

3xAA battery holder, cut a 5cm square of

corrugated plastic with a 2.5cm square cut-

out. Tape this to the underside of the

battery box and then stick it to the base.

Step 9

Connect up the circuit shown on the right. If you have the 2xAA battery

holder, push the battery snap firmly onto the battery holder terminals. If you

have the 3xAA battery holder then switch on. Run the program (click on the

green arrow) and check the motor shaft turns for 5 seconds and then stops.

Step 10

Disconnect the crocodile clips from the motor

terminals and clip them onto the lamp holder

terminals (screw heads) instead. It doesn’t

matter which way round you connect them.

Run the program and check the lamp comes

on for 5 seconds and then goes off.

Step 11

Disconnect the crocodile leads attached to

the lamp. Use them to connect the LED up

to the Crumble as shown (make sure the

metal ends of the crocodile clips aren’t

touching each other). Notice that the LED

has a longer and a shorter leg. The longer

leg needs to be attached to output A, and

the shorter leg to the negative (-) terminal

next to it. It doesn’t work if you connect it

back to front.

Step 12

Start a new program (click on File, New). Drag across

‘program start’, then ‘set A HI’. Next attach ‘wait 1

seconds’ then click on 1 and change it to 3. Finally

attach ‘set A HI’ and click on ‘HI’ to change it to ‘LO’.

Run the program and check the LED comes on for 3

seconds and then goes off. Save the program – call it

‘Light LED’.

Step 13

Disconnect the LED and its crocodile leads from the

Crumble. Switch off (if you have the 3xAA battery holder) or

unclip the battery snap from the battery holder (if you have

the 2xAA battery holder) to avoid draining the battery when

not in use. Your ‘Crumble controller unit’ is now ready to use

for the coloured spinner, traffic lights, chair-o-plane or

nightlight.
