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)

smart device that perform a certain function or solve a problem: program Arduino UNO to read signals from multiple input components to control multiple action components using Arduino C .

I've got my inspiration from my smart watch, here is my favorite feature in it which is called raise to wake addition to that i intend to add some adjusting buttons to help me customize clock.

raise to wake

Tool Chain

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

use to design the circuit and simulate

cardboard from any old device container

bread board

jumpers wire

Arduino uno

red LED

LCD I2C

3 push buttons

tilt sensor

adapter 5v

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?

okay as usually first step should surprise me 😅

i thought that it is possible to get real time by using just Arduino UNO but by searching i figure out that, this circuit needs a real time module like (DS3231 RTC) for example it is used to accurately provide the day of the week, date (DD/MM/YYYY), time, Unix time, and even temperature.

old an experience by Plouc in 2018

so i accept this challenge which mean that i will run this project without using any real time module, while searching i found someone who has faced this challenge before so i get his experience and his code from here.

so i got his code and his wiring and i start adjusting them step by step as below ⬇️

projecthub/simplest-uno-digital-clock-ever-

so first edit in wiring cause i have LCD screen I2C type so i change wiring to this diagram
then edit code for normal LCD screen to I2C screen which i have, to make it easier i use library which called
#include <LiquidCrystal_I2C.h>

in arduino IDE file then example i chose Hello World

i2c-lcd-arduino-tutorial

so after i make sure that screen is running well and push buttons i move to tilt sensor so first i test his circuit alone as shown ⬇️

my wiring for LCD I2C screen

then i start to marge his code to my code by delete those lines in his code which call normal lcd to run and back ground led to turn on or off replaced with easy function in library like
lcd.backlight();
lcd.setCursor(1, 0);

here some of code lines with comments to understand function of them

finial step is that i have to integrate two simple circuit together by using this wiring and coding.

here is the code i put into full code to add raise to wake feature ➡️

in Tinkercad site i didn't find tilt sensor so easily i have tried to replace it with slider switch then i write this code to make sure it works.

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?

first i try tilt sensor in simple circuit with led to make sure it works well

then i have to integrate two simple circuit together by using this wiring and coding

after i have run the code i found that it has big delay between the time i raise sensor and the background led to turn on or off around 5 seconds.
so as you can see it is impossible to be neglected so i go throwing the code to find solution

after some tries i figure out this problem where my commend is that turn push button when the tilt sensor sense LOW the problem is it delay until run push button and then start running for lcd screen.

so i solve it easy way by rewrite correct code to turn on or off LCD led at the same time directly after sensor had sensed.

first try = first failure 😅

enclosure

i cut 6 parts of cardboard as shown in this picture

then attach strap

quick and easy 😉

then i glow them together

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 found this problem in capture code which causes that PM change to AM at 1 o'clck and it should be 12.

so i solve this mistake by easy lines of coding where i divide this process to two parts one of them which increase flag once the hour = 12 and when hour = 13 it will change to hour = 1.

Final Project

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

finial the project works perfectly 💥

finial.mp4

WOW!

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

it will the power of comments (//) in the code which it makes reading so easier for other people so i appreciate every one who usually use them to help his pairs understanding his code and adjust it.

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.

i got my banner for this week from Bing image creator (Copilot ), just i write "smart watch beside Arduino and wiring" in generating bar then i chose one of them.
