Arduino for beginners. Part 10: Timer Interrupts

How to setup timer / external interrupts in an arduino sketch.

Well done. I like your teaching style. It it one of those videos that I will replay a few times to really absorb and try out what you said.

The presentation and explanation is excellent ! Please give the full code in one place ; while we are writing down the code to find if any error is made we have to go through the full presentation (to find out where we have made a mistake )

Thank you so much for the video sir.. very useful for me

[rursus]

Good! I'm going to use it in the lecture today.

Thanks for a great tutorial. I have watched it a number of times and i still do not under stand why you are setting the" mother LoopCounter equal the functionCounter in the statement" What is the purpose of setting the loopCounter to the value?

[heronpereira]

Would the timer interrupts itself? In case you put a small time for interrupt and lots of instructions that take more time than the interrupt.

thank you for the great video. in the playground link you posted for downloading the timer library, which one are you using? (there is another one that is linked by this "A separately maintained and updated copy of TimerOne is also available, supporting more hardware and with optimizations for more efficient code.")

Great content, very helpful. Thank you!!!

thank you for the video
I'm very new to Arduino and I was wondering if you can help me
I'm trying to do a 4 way traffic control using ultrasonic sensor but I'm having a problem with a timer
basically I want the red, yellow and green to work if a car falls within a certain distance and it stays there for a certain time.
lets say a car was within the distance between 10cm and 70cm the timer starts counting to 5 seconds and after 5 seconds if the car still there the red, yellow and green start.
I don't have an issue with the distance part but I'm having a problem with getting the timer to start when the car is within that distance and then test after 5 seconds if still there.

How to count timer overflow in Arduino mega2560 ?

[jakubstefanek]

Thank You :)
can multitasking/"interupts" be bypassed by more linked arduinos in a "cluster"
Can you make I2C/serial comm video with MASTER doing the high level taks and
slaves do the parael routines.

[UllulAmar]

how can I disable Timer1 interrupt ?
is there a statement that can undo < Timer1.initialize(length); > and < > only without affecting any other external interrupts ??

[mayurrajendra]

Sir, I want to learn library of timerOne so, from where i can start to learn. I wanted to start making my own simple libraries so please help me

[ljl]

In alternative, the use of millis() would not be ok?

[felixsaucedo]

is there any way to apply interrupts to PWM signal ?

[brunowtf_dk]

It is possible to make a timer, for example, 5 hours. instead of 2 seconds

Can you please write a code that i can upload in Arduino, I want a Small beep sound at 30mins, 1hr, 1:30hr, 2hr(all optional )
