Dear Mr Smyth
Thank you for sending us the details of your recent record attempt for 'Largest Joystick'.I
am afraid to say that we are unable to accept this as a Guinness World Record.
Unfortunately our research team have concluded that your attempt does not conform to
our manufactured articles guidelines as there is no commercially available joystick which
looks like a small version of this.
I appreciate that this may be disappointing to you, but I hope that this does not deter you
from trying again. We are always keen to hear from people who wish to set a Guinness
World Record. If you should need any advice regarding breaking an existing record or
setting a new Guinness World Record please contact us again through our website or
directly quoting the above membership number.
Once again thank you for contacting Guinness World Records. We wish you every success
with any future record-breaking endeavours.
Yours sincerely,
Sophie Whiting

1. Run the White/Orange and the White/Blue wire into
fire button hole
2. Attach the White/Orange wire to one pin of fire
button
3. Attach the White/Blue wire to the second pin of fire
button
Joystick Cable continued
4. Attach a short White/Blue wire to the second pin of
fire button
5. Run the other end of this White/Blue wire into the
joystick hole
6. Insert the fire button into the block
7. Wrap short White/Blue wire around the screw in the
base of the door stopper
8. Screw base of door stopper into the bottom of the
joystick hole
Joystick Cable continued
9.Run the Green, Orange, Blue, and White/Green
wires into the joystick hole
10. Wrap Green wire around Top rail
11. Attach Orange wire around Bottom rail
12. Attach Blue wire around Left rail
13. Attach White/Green wire around Right rail
14. Screw door stopper into base
15. Insert the 4 rails into their appropriate locations
Connecting Joystick
to Breadboard
Method:
Match the colour of the seven wires
already in the breadboard with the
colour of the six wires coming from
the joystick.
Next diagram is messy, sorry

Assignment 2
Write a program that will:
• Display “UP” when the joystick is moved up
• Display “DOWN” when the joystick is moved down
• Display “LEFT” when the joystick is moved left
• Display “RIGHT” when the joystick is moved right
• etc

Assignment 2
parallelput(1)
var value : int
loop
value := parallelget
if value = ______ then
put “UP”
elsif value = _____ then
put “DOWN”
etc

Assignment 3
Write a program that will:
• Draw 8 arrows (compass points) and a fire button
• Randomly highlight one of the 8 arrows and/or the
fire button
• Time how long it takes the user to match the prompt
with the corresponding joystick movement
• Repeat 20 times
• Output the total time taken for all 20 matches
• ?????? Additions ??????
