Wokwi Arduino Simulator Introduction

First of all, you have to visit https://www.wokwi.com
You can bookmark the site for easy access
Here are the quick links for the https://www.wokwi.com/arduino/libraries

How to get started with Wokwi Arduino Simulator?

First, go to https://wokwi.com
The basic layout is shown below

basic window of the Wokwi Arduino Simulator

The left side of the window is the editor window, where you can type your code or just copy-paste here. The editor supports very smart features which can be very helpful for code editing. the full features are listed later. The second window is the simulator window. here is where all the action takes place. The elements into the simulator are added via diagram.json file which we will see soon

Supporting documents

https://docs.wokwi.com/ hosts the preliminary helpful docs about the brief description. But, For now, I will share my own way of creating my projects in this

Start with any existing project. I will open this project, which is a simple Arduino Mega based blinky project.
Locate the diagram.json file. here is where the parts will be added or deleted.

Here is a brief description of the control buttons

Wokwi Arduino simulator window

A - diagram.json file - used to edit/delete/add components

B - project file - sketch

C - Play button

D - simulator window

E - maximise simulator window

I am going to add one more LED to pin 10 and change the LED colors. Red is boring.

I will locate the section in the diagram.json file, where I will change the LED color to RED

Now the simulator window looks like this

Now I will add another LED with the attribute as blue color and will connect it to pin 10 of UNO using the "connections" section. Please refer to the image below

So the code and the simulated window looks like below

Let's edit the code to blink the LED alternately.

you can also edit the code I have just edited here. The projects are very easy to share with others. The project I just edited can be accessed here. You can edit as well as your own copy.

Please post photos or videos of your projects once done. I will be happy to assist and see your projects here

For any questions and suggestions on the wokwi Arduino simulator, feel free to hop-in on to Discord server here https://www.wokwi.com/discord

Share your interesting projects and browse through several curious projects from fellow developers and makers on Facebook Wokwi Group!

Stay Safe!

Don't stop learning!

Code

sample code used

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

*/

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
  pinMode(10, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  digitalWrite(10, LOW);
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  digitalWrite(10, HIGH);

  delay(1000);                       // wait for a second
}
