Keep the execution time of all your functions very short.

In order to multitask with Arduino, follow those tips: In fact, the execution speed is still rather high for handling hardware.įor example, the ATmega328 microcontroller in Arduino Uno has a 16MHz frequency. Well, this is related to the global computation power. You may have heard that Arduino is not really powerful. Here is a video you can use as an additional resource to this tutorial (just using 2 LEDs).Īfter watching the video, subscribe to the Robotics Back-End Youtube channel so you don’t miss the next tutorials! Let’s start multitasking That’s roughly what is multitasking with Arduino, but at a much higher frequency. If you take one blue paper and one red paper, and alternate them very quickly in front of your eyes (at least 10 times a seconds), you’ll see the color purple.īecause the change between colors happens so fast, you’ll get the illusion that all colors are mixed into another color. Let’s illustrate this with an optical illusion. That’s the principle behind multitasking with Arduino. If you take small actions and do them very fast, one after the other, you’ll get a feeling of multitasking.

Every time you write something, you have to think about its impact on the whole code. So, if you decide to make a pause inside a function, then all your program is stuck waiting. A microcontroller has only one core, and is only capable of executing one instruction at a time. The “brain” of an Arduino board is a microcontroller (ATmega328 for Arduino Uno). With Arduino, things are completely different. For example when you start Firefox or Chrome, new threads will be created, so you can still execute all your programs while launching new ones.

You can install an operating system (such as Windows, Ubuntu, Debian, etc), and spawn hundreds of threads.

You are learning how to use Arduino to build your own projects?Ĭheck out Arduino For Beginners and learn step by step.Ī classic computer has multi cores and tons of RAM. You have to understand the difference between a computer such as a laptop or web server, and an electronic board with a microcontroller (Arduino). Why multithreading is not possible on Arduino

Task 5: Print the potentiometer value via Serial every 2 seconds.Task 4: Power on LED 4 if the potentiometer value is greater than 512.Task 3: Power on LED 3 if the push button is pressed.Task 2: Read user input from Serial (number between 0 and 255) and write the data to LED 2.Why multithreading is not possible on Arduino.
