Can someone explain timer interrupts to someone new?
There are a few ways to think about "timers" with an arduino. There are blocking timers such as "delay()" this literally stops the program for the time (mills) inside the brackets. This does not let anything else happen until the timer runs out. You can then use non-blocking timers, these require a bit more code but essentially the code runs as usual but at a certain time it can run a certain piece of code or function for example, this is more along the lines of an "interrupt" in the context of what I think your asking. BUT there are also true interrupts. This is used for inputs (typically) where no matter what part of the code the program is in, if the interrupt pin (depending on the board could be specific pins) is triggered, you can jump to a certain function in a code. Have fun. Google is your friend :) More on reddit.com

How to set a timer interrupt
I need a way to set a timer interrupt on an Uno R3. That is, after x second/milliseconds/whatever I need an interrupt to trigger. I've done a forum search, and there are posts that seem to make reference to timer interrupts, but I can't find the code to do it. More on forum.arduino.cc

December 4, 2022 - It now supports 16 ISR-based timers, while consuming only 1 Hardware Timer. Timers interval is very long (ulong millisecs). The most important feature is they are ISR-based timers. Therefore, their executions are not blocked by bad-behaving functions or tasks.

January 9, 2025 - Setting the TOIE bit on each timer’s interrupt mask register, TIMSKx, enables timer overflow interrupt. The 'x' here is the timer number and so for Timer2, the register is TIMSK2: Exactly when the overflow occurs depends on the oscillator frequency and the clock divisor. Hence, this is the Timer2 overflow time formula: The Arduino UNO board has a 16 MHz oscillator and the clock divisor is 64 by default.

r/arduino on Reddit: Easiest way to timer interrupts?
April 29, 2012 -

Hey guys,

i want my Arduino to execute a function every xxx ms, but want to avoid delay functions. Those don't take into account the time the function actually needs to be executed completely, so i'm thinking timer interrupts are the best way to do it.

Is there an easy way to make them work in Arduino? I'd ideally skip searching the documentation and calculate the register values, so maybe there is a library for this already existing?

Thanks!

April 5, 2023 - Overflow: In this case an interruption is triggered each time the timer overflows, meaning it passes from its maximum value back to 0, which in case of an 8-bit timer will be each time it reaches 255. Whenever the timer reaches to its maximum value say for example (16 Bit-65535) the Timer Overflow Interrupt occurs. Input capture interrupt: For Arduino UNO this can be implemented on timer 1.

November 28, 2024 - In both scenarios, you stop your current action. That’s why it’s called an interruption. You have to stop what you’re doing to handle the interruption, and only after you’re done with it, you can resume your action. Arduino Interrupts work in a similar way.
