Week 7

“Things Get Smarter”

Ideation

Alfred J. Pennyworth (Batman Begins)

Continued with Alfred Project in this week I decided to make Alfred more intelligent, more features with user-friendly interface to create (Alfred v2). :-)

Tool Chain

Software:

Electronics:

2x (330 Ohm) Resistor.
2x LED.
1x Slider Switch.
1x Arduino UNO R3.
1x IR Sensor. (HW-201)
1x LDR Sensor.
1x Temperature & Humidity Sensor. (DHT11).
1x Liquid Crystal I2C.

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?

Phases of making Alfred v2:

Design:

In this Part, I Used Fritzing to simulating the circuit wiring and design like circuit below:

Note that

Then I implement the real circuit:

An Enclosure for the Project :-)

VID-20211007-WA0033.mp4

Video For The Enclosure

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?

Coding:

The code running as follows:

First Thing we Include LiquidCrystal_I2C Library and DHT Library then define the DHT Configurations parameters of the lDR Sensor, IR Sensor, light fan, Val for store data, and LCD Configurations.

After this In Void Setup we begin the LCD, DHT, Serial connections in to start to communicate with Arduino then set the pin mode for each component.

In Void Loop, we declare the Humidity and temperature Variables for DHT then we can print the reads in the serial monitor if we want same for the lcd we print the values ofthe DHT readings on it.

And finally we make a variable to save the data from the Light sensor then typed if condition tell, that if the IR sensor doesn't see an obstacle then the FAN led and the Light_Value LED will be off.
And if the IR Sensor See an obstacle, then the readings if Light sensor will be mapped and read by the Light_Value LED.
And also will take us n another If condition that is the DHT read Temperature above 30 c, then the FAN LED will be ON Other than that the LED will be off.

Testing:

Testing the Real Circuit

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

I wasn't Know What's the meaning of I2C in the LCD and after a little research I found this useful video talking about it.

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

Problem: After I Integrate Every Module in the Circuit, the Light_Value Led wasn't functioning properly.

Issue: There wasn't a Variable to store the data from the Light Sensor.

Solution: Add a Val Variable to the cod to store the readings from the Light sensor, then continued with our code.

(like the Photo) :-)

Final Project

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

RC Car With Hand Geture Controller

The More I Know about how to use various of the modules, the better I'll make my 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?

This week we had an Optional session about soldering and it was so much fun :D❤
