Week 8 - 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)

RC Car

This week assignment is about Communicate wirelessly with a Smart Circuit via a Graphical User Interface (GUI) on your phone or PC.
I always want to have my won remote control car which i made.

So i take this week chance to make it.

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

Designing process

Software: Fusion360

Fusion360

Laser Cutting

Software: laserWork (used in prepare for fabrication process)
Machine: Morn MT3050D CO2 Laser Cutter
Material: Wood + M3 screws and nuts as well.

OUR LOYAL FRIEND

ONLINE TOOL

Google: To search for whatever i need to know to complete the assignment.
Tinkercad: The main tool in this assignment, As i made the electrical circuit in it to make sure from the idea and from its validity

Electrical components

Breadboard:
wires
9 Volt Adapter:
Dc Motor
Motor driver
wheels
caster wheel
Bluetooth Module

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?

Bluetooth Module
Tx to Rx Arduino pin
Rx to Tx Arduino pin
VCC to 5 out Arduino pin
GND to GND Arduino pin

ٍENA to pin 6 Arduino pinٍ

LN1 to pin 7 Arduino pin

LN2 to pin 8 Arduino pin

LN3 to pin 11 Arduino pin

LN4 to pin 12 Arduino pin

ٍENB to pin 13 Arduino pin

variable identifications.
Bluetooth incoming data .

Void setup

It has the dentification of the pin modes between input and output.

And make at the start of the program the motors off

Void LOOP

Start the Loop by checking the incoming data send by the Bluetooth to go on the loop and the different function

1- first option : if you press 1 in the GUI >> the action will be >> the car move forward

2- Second option : if you press 2 in the GUI >> the action will be >> the car move Backward

Void LOOP

3- Third option : if you press 3 in the GUI >> the action will be >> the car move Right

4- forth option : if you press 4 in the GUI >> the action will be >> the car move Left

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?

2 DC Motors with the Bluetooth module and Motor driver

I test all components to make sure that all of them work.(DC Motor - Motor driver +bluetooth)
I connect all the components together
Making sure from the connection with the Arduino and breadboard
Take the text code from tinkerCAD to Arduino IDE to compile it and upload it to the Arduino UNO
Connecting them to the 9 voltage adaptor

This video show the progress of the project

The Mobile app. control The DC motors by the Bluetooth module
Each arrow make the car move in a certain position

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)

I face a problem with the wires of the DC motor.

as the wire place was cut and i try to fix it many times Soldering Iron and soldering to make it works

And It is finally done

DC Motor wires

Perfect wiring

Final Project

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

bottom of the car

It will be a part of by final project.

WOW!

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

I think one of my dreams become true by making this RC car
