The top line and bottom line are connected perpendicular to the lines you use now. Those lines are for gnd and plus.
That smoke detector needs a separate power supply for the heater.
Maybe you can try to make a schematic how you want to connect things? Post it here. We will help you.
Another thing: take steps... first make the buzzer work, then the sensor, then the lcd..
Not all at once... it is almost a guarantee for failure...
The smoke sensor must use an external power supply for VCC and GND, but the data pin can be wired directly to the Arduino. The LCD should use external power connections for VCC, GND and A (anode) [edit] "A" not needed for I2C LCD [/edit]. The other devices can wire data and power directly to the Arduino. The breadboard is not needed.
the picture i posted was already a working process, and can i still use the breadboard since it is the only thing that i know?, also i just want to know how where can i add or connect the dht11 and lcd because these two are the only lacking to my connections
A what?
Yes, or read post #3.
Where did you get instructions to use the buzzer, flame sensor and smoke sensor?
A what?
i mean the flame, smoke and buzzer are already working
Yes, or read post #3.

my professor gave me this project he said to make a smoke and flame detector alarm and he wants me to add a room temperature indicator
You can find many LCD and DHT tutorials on the internet. Find some. If you have questions while you write programs for them, ask.

[/what do you mean with that?]

[/my sensors and buzzers are already working its just i dont know where i can connect my lcd and dht11 ]
Again.
That you are very likely to ruin the built in voltage regulator of the arduino as the smake detecor will take too much current..
With smoke detector I mean the thing with the shiny gauze.
I am wondering how long it will work.. (see above).
If you use the board properly, it should not be a problem to add the other stuff...
With properly I mean: use the power lines for power. Those have many more holes, so you do not need to put all in a tiny space like it is now...
Your other topic on the same subject deleted.
Please do not duplicate your questions as doing so wastes the time and effort of the volunteers trying to help you as they are then answering the same thing in different places.
Please create one topic only for your question and choose the forum category carefully. If you have multiple questions about the same project then please ask your questions in the one topic as the answers to one question provide useful context for the others, and also you won’t have to keep explaining your project repeatedly.
Repeated duplicate posting could result in a temporary or permanent ban from the forum.
Could you take a few moments to Learn How To Use The Forum
It will help you get the best out of the forum in the future.
Thank you.
can you guys show me a circuit diagram on connecting these components? and also i would like to add the dht11 and lcd module on the set up..pls., badly need it
I do not see you doing the neccessary effort...
That would be: follow hints and tips.
In case you did not know: we do not need to help you badly...
Again. Why do you bother people to do your work for you? Stop being defiant at doing any work.
