Final Project Journal

3D design :

I exported the cylindrical body as mesh and upload it on Cura software then added the 4 brackets.

i checked  dimensions that it is as i want , then start preparing the file with the following settings:
- infill 20

default layer height 0.2
- temperature 215/ 60

-no support 

the total print time was 8h  so we let  it to be overnight print with 80g 

-To print the design we took the g-code file, after checking the parameters and edit the speed and heat ,and upload it into the machine.
-first thing we unloaded the old filament and added the new one, started heating the nozzle and bed , the machine did calibration on the bed then the printing process started .

-I checked the first layer that it is okay.

RTC/wires/ nonpixel/ Arduino/wires/9v adaptor/regulator/LCD screen/ 5v adaptor/button/speaker/ joystick

first i built the  circuit using wokwi

then applied it on Arduino and breadboard 

include tests
- test RTC for the first time 

• test neopixel
  - test the LCD to write what on serial for RTC
  test buzzer alone

• integrate pushbutton

• test joystick with RTC

• then the full code

Pseudocode / code logic 

Initialization:

1. Initialize RTC (Real-Time Clock) module.

2. Initialize LCD display.

3. Initialize NeoPixel LEDs.

4. Set up input pins for joystick, OK button, and push buttons.

Main Loop:

1. Read real-time from RTC.

2. Display current time on LCD.

3. Check for joystick input:

   • If joystick pressed, enter setting mode.

4. In setting mode:

   • Allow user to input desired hour, minute, and second using the Joystick :
     as when moving up the time increase , move down time decrease , move left and right to move from hours to minutes .

   • Confirm settings when OK button is pressed.

5. Check for push button presses:

   • If push button pressed - case 1 , turn NeoPixel white.

   • If push button pressed - case 2, turn NeoPixel off.

   • If push button pressed - case 3, turn NeoPixel blue.

   • If push button pressed - case 4, turn NeoPixel off.

   • then iterate again 

6. Compare current time with set time:

   • If current time equals set time, fire buzzer.

First i jointed the base with the body using two brakets

mounted the speaker 

then ardino and breadboard
from the top i mounted the screen , led  and push button ,

i made sure that everything is working before jointing the top with the encluser.

Menna was very helpful along the journey from discovering the components together and check the problem of the encoder , to the design she helped me a lot with it .

also Mego and Diaa helped me a lot in the code as me and Diaa was having similar functions with RTC and Joystick and they worked a lot on the code to modify it.

One Challenge was using Rotary encoder ,gives unstable result as rotating once doesn't always trigger a clear reading.
it has 3 digital pins do the following  :

-CLK: Indicates rotation (0 or 1 on serial print).

-DT: Direction of rotation (0 or 1).

-SW: Button press (0 or 1) .

instead we used Joystick and it worked well with the code.

Another Challenge was working with curving shape like cylinder and mount components on it , it was the first time to design something not in form of boxes so it was a bit hard at the beginning. 

Despite i made the diameter of the enclosure 180mm which is ig the components almost fit in and there is no place for another bracket that made the base not fully fixed to the enclosure.

1. I  will make the design myself using fusion 360 to be like cactus.

2. add speaker and Bluetooth modules.

3. change the whole design.

4. use millis in the code do control the functions.

5. add snooze function and make it act a a reminder.

6. make it have memory to store different times .
