Week 8 - 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)
LCD
As my project has the LCD and the LED components so i start to think to control those two components through the Bluetooth module in week 8, to be ready for this in my project
LED
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
software : Tinker cad to simulate the circuit online, and a little bit with Fritzing
Arduino Bluetooth Control to control Bluetooth module
Arduino software to write the code
materials: Arduino uno , LED, LCD, wires, resistors,
mobile phone, breadboard.
Arduino Bluetooth Control
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?
VID-20210911-WA0003.mp4successful trail with Android GUI
I started by watching the videos of the exercises for week 8, and practice it, here some of what i did, I started by simulate the circuit on tinker cad and write the code with the instructor on the Arduino software then try it with the real components
faild trail with the PC GUI
A trail for LCD code without any other component:
//YWROBOT
//Compatible with the Arduino IDE 1.0
//Library version:1.1
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27,20,4); // set the LCD address to 0x27 for a 16 chars and 2 line display
void setup()
{
lcd.init(); // initialize the lcd
lcd.init();
// Print a message to the LCD.
lcd.backlight();
lcd.setCursor(3,0);
lcd.print("Hello, world!");
lcd.setCursor(2,1);
lcd.print("Ywrobot Arduino!");
lcd.setCursor(0,2);
lcd.print("Arduino LCM IIC 2004");
lcd.setCursor(2,3);
lcd.print("Power By Ec-yuan!");
}
void loop()
{
}
The components that i used in my circuit, and the 5v adapter
i couldn't find the hc_05 component on fritzing, so i searched on youtube till i found this video
I download it from this link
then i searched for how to wire the lcd
and searching for how to simulate the circuit on youtube, and how to simulate the lcd on fritzing as wiring the lcd on real is different from the software
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 started by searching for how to use the lcd and how to write the code on the Arduino, i found this links that helped me
then connecting each part alone , so first the the LCD to check if its working or not
20210911_131627.mp4then checking the Bluetooth module
Title of Media
some links helped me:
https://github.com/fdebrabander/Arduino-LiquidCrystal-I2C-library
https://www.arduino.cc/en/Tutorial/LibraryExamples/HelloWorld
then the checking the led
The circuit
then write the code of the led
Then adding the library of the LCD as shown in the video
then adding the the code of the Bluetooth module to the circuit
here i found a challenge with the lcd, there is no word appear on the lcd
20210913_170332.mp4i searched for the reason, till i found i could adjust the lcd with screwdriver in this white whole
20210913_202011.mp4WhatsApp Video 2021-09-13 at 8.11.30 PM.mp4And finally its done
the outcome of the lcd
WhatsApp Video 2021-09-22 at 4.07.57 PM.mp4The code that I used
//YWROBOT
//Compatible with the Arduino IDE 1.0
//Library version:1.1
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#define led1 2
#define buzzer 7
char incomingdata = 0;
LiquidCrystal_I2C lcd(0x27,20,4); // set the LCD address to 0x27 for a 16 chars and 2 line display
void setup()
{
Serial.begin(9600);
pinMode(2, OUTPUT);
pinMode(7, OUTPUT);
lcd.init(); // initialize the lcd
lcd.init();
// Print a message to the LCD.
lcd.backlight();
lcd.setCursor(3,0);
lcd.print("Hello, world!");
}
void loop()
{ while (Serial.available()>0)
incomingdata = Serial.read();
if (incomingdata == '1') {
digitalWrite(led1, HIGH);
lcd.clear();
lcd.print("drink");
delay(500);
digitalWrite(buzzer, HIGH);
delay(1000);
}
else if (incomingdata == '2')
{ digitalWrite(led1, LOW);
lcd.clear();
lcd.print("water");
delay(500);
digitalWrite(buzzer, LOW);
delay(1000);
}
else if (incomingdata == '3') {
digitalWrite(led1, HIGH);
lcd.clear();
lcd.print("everyday");
delay(500);
digitalWrite(buzzer, HIGH);
delay(1000);
} else {
digitalWrite(led1, LOW);
} }

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?
I faced lots of challenges through trying to pair the Bluetooth with the mobile phone
Title of Media
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
As i will use the led and the LCD in my projects but without using the Bluetooth module by using the push button,
so this a great trial for my to do this before starting next week
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

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.
