ESP32 simulator with Neopixel interface. Learn ESP32 coding online - Use Wokwi ESP32 simulator for your next project!
This project will show how to connect an LED ring to an ESP32. You can program ESP32 simulator using Arduino or Micropython programming. Wokwi ESP32 simulator allows you to run ESP32 code right out of the browser. Sharing the ESP32 projects is easy. You just have to share the link with others. Everybody will be able to run the project online and also create their own versions.
Step to simulate ESP32 online on Wokwi
There are two options.
Option 1 - Select `ESP32` as the new project option
Option 2 - Select `Micropython on ESP32` as the new project option
Choose between ESP32 on Arduino Core or Micropython on ESP32 option - Wokwi online ESP32 simulator
