Week 7 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

pinball DIY.

my inspiration from the pinball game, l really love this game.

these videos help me to organize my idea: wooded pinball

when the ball crosses the IR sensor, some LEDs play with a pattern with a sound from the buzzer.

And if the ball moves around the microwave sensor, some LEDs will play with another pattern with another sound from the buzzer.

The motor is running all the time.

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

Circuits designed on TinkerCAD.

The first part includes:

IR sensor.
3 LEDs.
3 resistors (each one 220 Ohm).
Arduino UNO.
breadboard.

connection:

red LED on pin 2.
yellow LED on pin 3.
green LED on pin 4.
signal pin of IR sensor on pin 5.
buzzer on pin 9.

Code on Arduino ID

having one input (IR sensor), and 4 outputs (three LEDs and a buzzer).

those outputs will be on according to the IR sensor.

if the sensor read a high or low (when the ball moves in front of the IR sensor), then the outputs are on with sequence.

else off all of the outputs.

first, declaration of pins and mode of it (inputs or outputs)

make a variable to sort in it the value of the IR sensor.

To know the reading of the sensor, use the serial.

the sensor always read 1 (high).

if anything in front of it will read 0 (low).

the rest of the code.

Testing on TinkerCAD.

copy the code from ID Arduino and paste in the code of TinkerCad to test the circuit.

Circuits (2) designed on TinkerCAD.

The second part includes:

motor.
on/off switch.
wires.
5v adaptor.

Circuits (3) designed

The third part includes:

RCWL-0516 microwave sensor.
2 LEDs
buzzer

connection:

red LED on pin 6.
white LED on pin 7.
signal pin of microwave sensor on pin 8.
buzzer on pin 9.

Code on Arduino ID

To know the reading of the sensor, use the serial.

the sensor always read 0 (low / no motion there).

if anything moves around the sensor it will read 1 (high).

first, declaration of pins and mode of it (inputs or outputs)

final code

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

testing all component together

2 input (IR sensor and microwave sensor) and outputs (LEDs and buzzer)

building pinball machine from cardboard

cut rectangle 25*32 cm

cut 2 sides and front part

part of moving part

fixing with glue gun

cut small piece from strew to moving part, and the other side to shaft of motor.

fix it

the other side

fix switch in side of machine

connection of motor

fix the two sides

connect positive of LED to female-male jumper and negative to resistor.

fix IR and 3 LEDs

fix microwave sensor and 2 LEDs

all parts

tools for hand part

fixing wood .

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

DC motor not working at 5v, so replace it with 9v

replace hand part with wood clips it is easy and the same effect.

wood clips

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

pinball machine

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

in the Midweek session, the part about finding the bugs in code. it is really a very nice part.

Making a smart home system in EO week session.
