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)
Build a simple smart circuit that contains at least TWO action components that you can control wirelessly.
Use either the Android GUI or PC GUI to control the action components
Tool Chain
Which software/machines/materials did you use in the assignment? Why?
Ardiono IDM:
to wirte down the code
Arduino bluecontrol:
control the code wireless
Tinkercad:
design the cuircuit but it doesn't have the blueotooth device.
Title of Media
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?
Tinkercad design, imaging that there is bluetooth device
I tried to design the cuircuit on tinkercad, but I couldn't find bluetooth device. So, I used the connections from tinkercad then I added the bluetooth connection to it.
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?
Materials:
Bluetooth module
arduino uno
Jumpers
resistors (1K, 560, 220)ohm
buzzer
RGB led
breadboard
I connected the wires, then tried many times and it wasn't work. So, I foundout that I need to dissconnect I/O inputs during the uploading.
after the code uploading, I tested the conditions and it works.
the conditions:
entering 1 -> red light
entering 2 -> green light
entering 3 -> blue light
entering 4 -> no light
anything else -> buzzer alarm
the code:
// Definig the constant integers we will use in the circuit by their pins no.
const int buzzer = 2;
const int redPin = 11;
const int greenPin = 10;
const int bluePin = 9;
char incomingdata = '0'; //character variable with initial data = 0
void setup() {
Serial.begin(9600);
//Defining the color lights and buzzer as outputs
pinMode(redPin, OUTPUT);
pinMode(greenPin, OUTPUT);
pinMode(bluePin, OUTPUT);
pinMode(buzzer, OUTPUT);
}
void loop() {
while (Serial.available() == 0);
incomingdata = Serial.read(); // reciving the read from the mobile app and store it in incomingdata variable
// the conditions are if the recived data =1, red light is on;
// if the recived data =2, green light is on
//if the recived data =3, blue light is on
//if the recived data =4, no light is on
// else any number is going to turn the buzzer on
if (incomingdata == '1') {
digitalWrite(redPin, HIGH);
digitalWrite(greenPin, LOW);
digitalWrite(bluePin, LOW);
} else if (incomingdata == '2') {
digitalWrite(redPin, LOW);
digitalWrite(greenPin, HIGH);
digitalWrite(bluePin, LOW);
} else if (incomingdata == '3') {
digitalWrite(redPin, LOW);
digitalWrite(greenPin, LOW);
digitalWrite(bluePin, HIGH);
} else if (incomingdata == '4') {
digitalWrite(redPin, LOW);
digitalWrite(greenPin, LOW);
digitalWrite(bluePin, LOW);
} else {
tone(2, 523, 2000); // play tone 60 (C5 = 523 Hz)
}
}

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?
yes, cause at first I used servo motor but it didn't work. instructor adviced me to change it. So, I used RGB led.
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?
when the servo motor wasn't working I changed it to RGB led.
when the arduino wasn't uploading the code, I disconnected the I/O inputs of the bluetooth device.
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
It will help me if i wanted to connect the device wirelessly.
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
may br the hackathon was cool, but I didn'y attend it
