You will need:
Parts included in class kit
▪1 Crumble controller unit (see Crumble blog 1)
▪1 sheet of corrugated plastic 16.5 cm x 16.5 cm
▪2 crocodile leads
▪1 motor
▪1 motor mount
▪1 motor pulley
▪1 card disc

Step 1
On the sheet of
corrugated plastic,
use the ruler and
pencil to mark out the
base, upright and
support as shown on
the right. Cut the parts
out neatly. Slot the
support onto the
upright (you may
need to adjust the slot
length to allow the
bottom of the two
parts to line up). Glue
these to the base.
Step 2
Draw around the coin
on the card disc. Colour
in the disc with
alternating primary
colours. Push the pulley
onto the motor shaft
with the nose pointing
away from the motor.
Push the disc onto the
nose of the pulley.

Step 3
Remove the plastic film from the bottom of the motor
mount and stick it firmly onto the upright. Make sure
the coloured disc isn’t touching the top of the upright.
Step 4
Use the two crocodile leads to connect from the motor
terminals to the Motor 1 terminals on the Crumble as
shown. If you have a 2xAA battery holder, clip the battery
snap connector onto the battery holder terminals. If you
have a 3xAA battery holder, switch it on. Select the file
‘Run motor’ from the Crumble folder. Click on the green
arrow to run your program, and check the disc rotates.
Ack
Step 5
Click on ‘5’ seconds and type in
different values to change the
length of time for which the disc
rotates. Click on ‘50’ and type in
different values to alter the
speed of rotation.
Step 6
You can try colouring in discs
with different colours or
patterns to see what effects
you get when you rotate them.
Step 7
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) when not in use to avoid draining the battery.
