I believe this quote makes me sane in this extra amazing and full of strength week:
“You deserve the best, the very best, because you are one of the few people in this lousy world who are honest to themselves, and that is the only thing that really counts.”
― Frida Kahlo.
This week assignment was to design and program a smart device that perform a certain function or solve a problem, while using Arduino IDE to write the code.
The device must read signals from multiple input components (Sensor, Switch, or variable resistor) to control multiple action components (Motor, Buzzer, LED...etc) and useing Arduino IDE to write its code.

I decide to create a social distancing detector alram as I get inspired by this video. this choose was to gaine in depth understanding about sensors ,how it function and how to write a correct Manuel code instead of code blocks.
This third design idea was to control a servo motor and 2 LEDs with ultrasonic sensor while changing the inputs acording to the swich button state on or off.
The software that I used:
Tinker-cad ,To create and simulate the first LiquidCrystal LCD circuit that I do't have with me right now and Arduino ID to write the code
The physical component that I used to creat my new/second circuits with the LED that I have are:
Bread board.
Jumpers.
RGB Led.
LiquidCrystal I2C LCD.
PIR Sensor.
Buzzer.
Ultrasonic senso.
resistors 220 ohm.
Arduino UNO.
1 k ohm Potentiometer.
After creating the circuit I used Arduino IDE to write the code.
The prototype materials that I used are :
Cardboard.
Plastic tape.
The physical component that I used to creat my third circuits are:
Bread board.
Jumpers.
2 Leds.
Ultrasonic senso.
2resistors 220 ohm.
Arduino UNO.
Servo motor.
on off switch.
1 k ohm Potentiometer.
I started by using TINKERCAD program to simulate my circuit , as I opened the Tinkercad and Sketched the parts of the design on it ,after finishing the sketch process , I generate the code and it works after 17 or more hours of try and fail process that I learn much through it.
AS I started to perform the circits physically it turn out that I have a LiquidCrystal I2C LCD insted of the regular LiquidCrystal LCD taht I sumilate on tinkercad. I started to search about this LED name and how it works.
I simulated my first circuit with the LCD on tinkercadto make sure it works.

I used Arduino ID to write my code.
Arduino Integrated Development Environment (Arduino ID) is a cross platform application used to program Arduino compatible boards. It is a place to write the codes responsible for programming Arduino using C and C++ functions. Arduino.
The first process with to simulate the circuit on tinker-cad ( it is optional but I needed to do it in order to gain more understanding of electronics ).
The second process was to code the circite , so I started to read about LCD,PIR Sensor,Buzzer and Ultrasonic senso codes and how to read and write it from ARDUINO reference website.Also, I write ech code one by one in order to learn about different posible syntax or the logic error that I may have. The code pins are written on the code below.
I creat the code 6 time and it was do all the function without me moving the sensor or anything !! I try my hard to write the code but somehow I ended copy paste the video code and rewrite it to be my own. It's not the best option that I'm aming to but it's a good step for me.
After the simulation went will,I find out that the lCD that I have is a different type so I learned about it and start to assemble the circuit physically as it's not in tinker-cad simulation.

In order to make sure the problem that I had is with my LCD, I used hello world code that exist on Arduino ID built in examples. And I used This Articl as my reference.
It turn out that my LCD isn't working right, as it shows H and Y letters instead of hello world phrase,The following video shows the LCD outcome and connections in more details
The second code part 4
After assembly the component physically, The LED, PIR Sensor,Buzzer and Ultrasonic senso works but the LED started to blinking and have a blocks of light that worked for one to two minutes and then it light fully without my messages. I believe either the LED damaged or my code have logical condition error that I can't figure out.

Hello world code part 2
As advised from my instructor I created another more simple circuit and it works great.The circite was inspired by a previous deiploma colleague Bishoy Attif week7 assigment at profile.
I didn't preform a tinkercad simulation, I choose to do it physically after changing some details on the code and the circite.
The following video is for my third circuit after assemble it :

I asked for help regarding The current through the backlight LED on slack and my colleagues and Saeed helpd me to solve the problem.
Also, I learned alot while helping my colleague Amr in last week activity.
Alot of colleague asked for help and helped each other on slack this week, and I belive it answer alot of question that I have too.
I know that I should ask for more help to save myself lots and lots of hassle but I prefer a self learning time where I can grow more and learn. I'm planning to ask my group instructours this week about the code and the LED matter.
As promised I asked my instructor help and show him my code and circite so far, he try to help as much as it possible, and he says that my code is right and he can't find anything wrong with it, so he advice me to make the circite more simple and I'm considering his advice.
My USB-C to USB adapter suddenly stoped working, I wasn't aware of it till I try to practice my mid week assignment. So I ordered a new one from Saturday and it didn't come yet. Untill it comes I try to make sure that the tinkercad simulation and the code is correct and I hope it turns right when I preform it physically.
The usb that I order is heated the lab and the Arduino so much ,so I'm returning this Sunday and I'm looking for a new one online. So if you could recommend on for me it will be a great help.Thanks.
I'm still in the process of learning coding and detect my proplems.This week and the last one toke me more than 20 hours of learning and still I'm not even a beginner but I will do it I know I can !!!
This week is very weird to me, I thought I would hate to straggle with coding and Tinkercad simulation and so on, but I love it so much.
I spend 8 hours everyday trying to figure out how things work, and I'm still a beginner but I love the process so much.
After finising my tinkercad simulation and starting to do the circuit it tearn out that my LED is LiquidCrystal I2C not LiquidCrystal, this LCd type is extremely similar to LiquidCrystal LED but with a diffrent library, connections and not exist on tinker-cad.
So I decided to document the two codes and learn more about LiquidCrystal I2C LCD in order to do my assigment and learn more about coding and electronics.
My third design works so will from the first try !! It wasn't expected, I thought it will take very long time as usual. I'm blessed as it gives me extra time to focus on my final project coding and design.
I believe that I will use all the knowledge that I leaned to create and code my final project.
Last Saturday I have had an amazing extra activity with Eng. Sherif Rashwan. The Topic was Soldering Electronic Components to a Perforated Board.
You can find all the information and material related to this session at the following Drive link.
Ps. They didn't took my picture, so I decided to add some photos of my amazing, creative and hardworking colleagues that I attend the sesion with. Also, on that session I received so much help from instructors Maha and Amany and I'm greatly thankful for both of them.
