ESP32 Simulator - LED chaser project 🎉😍-2022

Introduction

You can use the ESP32 simulator to learn ESP32 programming. You learn ESP32 programming faster. Since the ESP32 simulator by Wokwi is web-based, you can access the projects anywhere. Wokwi ESP32 simulator runs on all platforms Windows, Mac, IoS, Linux, Android, and more...

In this project, there are 10 LEDs connected, all to the ESP32 via a current limiting resistor. You can change the color of the LEDs and wires by editing the diagram.json file. The programming is very similar to how you program Arduino boards!

Wokwi is an online embedded systems simulator that supports ESP32, Cortex M0 based Raspberry Pi Pico board, and more

Things you need

• ESP32 module
• 10 LEDs
• Connecting wires
• Embedded systems simulator (wokwi)
