Multi-tasking, Multithreading, or Hyperthreading with Arduino

Technically you cannot multithread with a single Arduino microcontroller. However, we can simulate multithreading.

Great tips. One thing to keep in mind is that if you stay in a while loop, the particular code you wrote will not allow the LED to continue blinking.

SERIOUSLY THIS IS AMAZING! I was dying trying to figure out multitasking on my tft computer i'm making, and this worked perfectly! I also didn't know you could read microseconds so that was helpful to!

This looks like the code I’ve been looking for to run 3 stepper motors simultaneously or at least as near to simultaneous as possible. Thank you!

[sharath_naik]

Thank you for THIS! Have been sharing this video when people ask me about Millis.. Also you have a good programming sense..

[Jobobaboss]

Great video sir! Thanks a lot! Those time/lasttime/elapsedtime is just what I needed. Also I didn’t know about different functions one can make and call upon.

P.s. I’ve heard that you’re planning to make a new video about this in the future. Maybe for next time, do some practice calculations to see how that system of keeping track of time works. (Why do we need to code these calculations like we do, what does it do after a few cycles/loops. Why does this little ‘keeping time’ system work so good..) I’m sure many people (like me) are quickly confused when dealing with these calculations. But for the rest, great video. It was very helpful!

I think there's still one little issue with this example. If you keep pressed the button the program will stall on the while(buttonPressed) loop, thus the led won´t blink until button is released. Perhaps adding the logic to avoid that would be great!

I think nowadays it's easier to use freerts tasks, because in case you have 2 cores (like in esp32) you can even have 2 tasks running at the same time. This solution is nice, but it's really hard to manage once you have several different things going on.

Really helpful. Thank you so much. Subscribed. Cheers J

I was using it to read button input too. Thank you!

Hello sir, good evening,
Am creating a program 20Khz PWM signal for pump. It's absolutely working fine, when I wrote 2nd millis function and upload same board but 2nd program is not properly worked. Any solution for this sir ? Am using Arduino UNO board.

[AussieTrucking]

so how to write something after 'hello'? so 1 press 'hello' 2nd press 'world' then back to 'hello'

[brandonbarr]

Why not the short int button = 8? Yours is much longer

[pruthvijagadeesh]

what if the two tasks are dependent to each other? at that time how to handle to events simultaneously

[Khujandiho]

How would you program button that create 8 or so binary code. For example 1 push. 0001. 2 push 0011 e.t.c?

Heya.. im facing a little problem with the pid line follower...im using a diy ir sensor array of 6 the pid is working great and the library is kinda working but when i look at the values it kinda returns weird values sometimes which throws off the pid algorithm...do you think qtr library cant be used with dir sensor array?

[PerchEagle]

shouldn't you use unsigned long ?

[jhunmichaelibanez]

In the end you used all 3 of them in the title XD

[djaminepira]

thank you for the video, please help me i want to creat in incubator but the lcd result work with delay of servo motor not with theme delay exmp : dht11 delay (10), and servo (500), the lcd show result of dht11 with delay (500)

'Anytime more than 16ms, you should then use millis();'

Bro its not multithreading..i can say multitask using time base...any way explanation is nice good work...but change heading 😎
