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)

A Smart Device to Warn the Driver of the Car

The Smart Device Helps the Driver of the Car by Giving Accurate Data on the Distances between the Car and the Car in Front of him

Which Helps the Driver to keep a Safe Distance

Thus, it Helps Reduce Accidents

Tool Chain

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

Website tinkercad
Arduino IDE Program
USB Cable Arduino
Arduino Uno
Ultasonic Sensor
Jumper Wires
Breadboard
Buzzer
LEDs ( Red, Green,Yellow)
SlideSwitch
cardboard box

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?

Tinker Cad Warn the Driver of the Car

I opened the tinkercad website

I choose from a list Component ( UltasonicSensor - Buzzer - Arduino uno -SlideSwitch - LEDs- Resistor 220 Ω - LCD )

Connect the ends of the components using wiring

connection:

trigger pin UltasonicSensor on pin 2.
echo pin UltasonicSensor on pin 3.
Red LED on pin 4.
Yellow LED on pin 5.
Green LED on pin 6.
Buzzer on pin 7.
slideSwitch on pin 8.
Scl pin LCD on pins A5.
SDA pin LCD on pins A4.
I Wrote the Code
I used Simulation to Make Sure the Circuit Worked

inputs is (UltasonicSensor - slideSwitch )
outputsis ( Buzzer - LEDs - LCD )

code:

I Added my Libraries at first.
I defined a variable
Then Defined all my Components and Divided them into Inputs and Outputs.
Slideswitch must be turned on for the device to work
If the distance in front of the car is greater than or equal to 50 cm
A message " Safe " will appear on the LCD and GreenLed lights up
else if the distance in front of the car is less than 50 cm and greater than 30 cm
A message " Be careful " will appear on the LCD and the yellow LED will light up

else if the distance in front of the car is less than 30 cm
A message "Dangerous " will appear on the LCD and the Red LED will light up

And the buzzer works

OFF

Safe

Destance > 50 cm

Be careful
Destance < 50 cm
&&
Destance < 30 cm

Dangerous

Destance < 30 cm

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?

I connected the wires as in the circuit diagram shown earlier
I used an Empty Cardboard Box to Hold the Components Inside
to Simulate a Car

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)

1- I had a problem installing liquidcrystal I2C library
I could not find the required library

With the help of Instructor the problem was solved using an alternative library

2- I encountered a problem while connecting the clck terminal and the data terminal of the LCD with the Arduino

With the help of the Instructor, the problem was solved

It turned out that the error was in the reflection of the sides between A4 and A5

Final Project

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