Create Your LED Chaser Project Using Wokwi Arduino Simulator

  1. Open the wokwi Arduino simulation for a simple LED blink page here. Note that wokwi Arduino simulator even works on your mobile browser as well
  2. Once it is open, you can see two sections. To the left is the Editor window. Simulation windows is in the Right.
  3. diagram.json file is used to define the new elements and their connections respectively. Go ahead and have a look once. The ReadMe file is to share the information about the project and the source of the code etc.
  4. I have renamed the in the file from blink to LED chaser to make it more meaningful.

Please leave a comment if you have any questions. I will be glad to help you out

We will see the changes done in the INO file and JSON file
