Week 1 - Journal

I just wanted to control LED and buzzer with Bluetooth to finally do the last assignment

Tool Chain

software i used it to write the code of my

LMS 35 Temperature sensor

software to simulate my circuit and try it.

ATMega hardware arduino

Design/Preparation Process

char incomingdata = 0;

#define buzzer 3

#define Led 2

void setup(){

pinMode(buzzer, OUTPUT);

pinMode (Led, OUTPUT);

Serial.begin(9600);}

void loop() {

while (Serial.available() > 0)

incomingdata = Serial.read();

if (incomingdata == '1') {

digitalWrite(Led, HIGH);

}

else if (incomingdata == '2') {

tone(buzzer, 1000, 100);

delay(1000);

tone(buzzer, 1000, 1000);

}

else if (incomingdata == '3') {

digitalWrite(Led, HIGH);

tone(buzzer, 1000, 100);

delay(1000);

tone(buzzer, 1000, 1000);

}

else {

digitalWrite(Led, LOW);

noTone(buzzer);

} }

I wanted mainly if i click one

turn on led

if I clicked 2

buzzer generate sound.

Development/Implementation Process

and Finally i controlled LED and buzzer wi

Community of Learning

I keep trying to rewrite the code and rewiring for more than one hour, but when I posted my code on slack MARWA YASSER find out a bug in the code and the project worked after her comment

Overcoming Challenges

A lot of mistakess xD

i wrote Serial.print(9600);}

i should write Serial.begin(9600);}

I wrote while (Serial.available() == 0)

i should write Serial.begin(9600);}

Final Project

i wish i can make the AIR POLLUTION warner wirelessly

WOW!
