Hello,I want to make this project in real life and I want to buy the component from online shop plz can anyone tell if these are all the component I need or I need any other.
(I need to make temperatury control system where when the temp go below 20dC the heater is on(red led act as heater) and when the temp goes above 30dC the cooler turn on (blue led acts as cooler))
A 9V battery is a poor choice for powering your project. It’s expensive, has limited capacity, and you might end up replacing it several times a day. Instead, consider using a mains power source, such as a wall wart, which is more reliable and cost-effective.
Before proceeding further, what research have you done? Try searching for the term "Arduino temperature controller" I found plenty of examples complete with code that might be helpful for your project. Let us know if you need guidance on specific aspects!

I understand the OP is a beginner, but that is probably the laziest post ever on the forum.
Untrimmed screen shot, no code or links..
Sorry, but you’ll learn that you get more from life when you put more in.

Do you have the tools to make the rectangular hole in a panel for your rocker switch? Do you have the soldering iron and solder to attach wires to the switch terminals?

link please as you havent provided enough information
Could you clarify what you mean by "fir"? Are you referring to a type of tree, an acronym, or something else? Let me know so I can assist!
Please keep in mind that we are not a free design or code-writing service. We’re more than happy to help with your design or code, but we need you to make an initial attempt. Please design and write your code, then post it along with an explanation of what’s not working properly.

Show Your Work First: Before asking for assistance, make an attempt to design or write the code yourself. Share your work along with details about what isn’t working. Only you know what you want!
-
Provide Clear Documentation: Since we can’t see your project, share an annotated schematic (best) or a clear drawing of your setup. Pictures are welcome, but avoid using Fritzing diagrams as they are wiring diagrams, not schematics, and are not ideal for troubleshooting.
-
Include Technical Details: If there is specific hardware involved, include links to technical information. There are often many versions of similar components, so precise details are essential. What version of buttons buzzer and a stepper motor are we looking at.
-
Reference Resources: For additional help, check out useful links and tutorials: Useful Links on Arduino Forum. Post links to your buttons buzzer and a stepper motor technical information.
-
Obtain a copy: of the Arduino Cookbook and complete several of the projects. Many of them will help you achieve parts of your goals.
