Hi everyone,
I’m working on a project where multiple sensors are connected to my Arduino board, and I’m facing delays while reading and processing data. What are the best practices to make the code run more efficiently? Should I use interrupts, or is there a better way to handle multiple inputs?
Any suggestions or code examples would be really helpful. Thanks in advance!"
How would any one know if you have not actually posted your code?
You might want to look at this How to get the best out of this forum before you proceed any further.
We only know what you tell us, and without knowing what you have, and why you want to do this, we don't stand a chance.
What sort of Arduino board are you using?
How is it wired up? Schematic please.
After you do what is in post 2, study the several tutorials on the forum on doing many things at once and maybe state machines as well. These processors are many times faster than what I used commercially, so it's not the Arduino that's the bottleneck.
Your topic does not indicate a problem with the Arduino Command Line Tools and therefore has been moved to a more suitable location on the forum.
That can depend a lot on which sensors you are using, and how you use them. As an example, the DS18B20 temperature sensor can take up to 750mS between when you request the temperature, and when the temperature data is available to read. The simplistic method of using the sensor simply waits with a delay() while the reading is taken, while more efficient code will request the temperature reading, then come back and read the data 750mS later, allowing other code to be executed in the intervening time.
Hello abuturab02
Welcome to the best Arduino forum ever. 
Make software objects to handle several sensors.
remove all code (including debug prints) that are not mandatory.
make measurements how fast every individual sensor can be read
check if there are async ways to read a sensor (as @david_2018 said in #5)
do not read sensors more often than needed.
Addressing Your Issue:
You can spend weeks spinning your wheels, or you might get lucky and solve your problem quickly. To avoid unnecessary delays, it’s crucial to provide an annotated schematic of your circuit as you have it wired, showing all connections, including power, ground, and power supplies. I recommend it be in English, you can translate before posting if needed.
Why Detailed Information Matters:
Annotated Schematics: These are essential because they show exactly how your circuit is set up. Without them, it's difficult for anyone to understand what you’ve done, which makes troubleshooting nearly impossible. Fritzing diagrams or unclear pictures are not enough. A good schematic can save days in time when problems occur.
Technical Information: Many modules look similar and may even have the same name, but they can function differently. This is why we always ask for links to detailed technical information, not just sales pages like those on Amazon, which often lack the specifics we need.
Post your Software Without that we do not have a clue as to how it is expected to operate. Be sure to use code tags.
Show All Connections: It’s important to include every connection, especially power, ground and power sources in your schematic. Missing these details makes it hard to determine if a setup issue might be causing your problem.
My Process:
When I see a question, I spend a moment assessing it. If it’s missing critical information, I might ask for it. However, if it's repeatedly lacking important details, I may assume the questioner is not serious and move on to another query.
What You Need to Consider:
We don’t know your skill level or what resources you have available. If you’re missing key technical details or seem unprepared, it may indicate that you need to spend more time learning the basics before starting your project.
Providing the right information upfront will help you get the best possible assistance and avoid the frustration of running into dead ends. Let us help you by sharing what you have clearly and completely!
posting the code will provide some insight on "what" you're trying to do.
the answer to your questiion depends on
Just for your education, interrupts cannot or should not read data inputs. They can only tell your program there is data to be read.
