1 place 2 answer 'em all - Arduino, ESP32, embed Simulators

I will answer all the frequently asked questions about the Simulators for Arduino and ESP32. Let's get started. Wokwi is an online embedded systems simulator. It is free to use, easy to use, easy to share projects, and more. Let us dive into questions 🤿

1. What is the best Arduino Simulator for beginners?

Several Arduino Simulators have come in the past. Some are outdated. Some have stopped updating for newer OS. For beginners, I propose the following Arduino simulators. The list is based on whether it is free, ease of use, ability to share projects (in forums for help, for example), orparts available. Here we go

• Free Wokwi Arduino Simulator (https://wokwi.com)
• Free Tinkercad Arduino Simulator (https://www.tinkercad.com)
• Partially free Virtronics simulator (https://virtronics.com.au)

2. How to Use Arduino UNO is an Arduino Simulator?

To use Arduino UNO in an Arduino simulator, You can start with the template projects:

• Open https://wokwi.com
• Click on the Arduino UNO thumbnail
• This will take you to the empty Arduino UNO template page.

You can follow the same steps to add Arduino Mega, Arduino Nano, and other boards in the Arduino simulator.

3. what are the benefits of using an Arduino Simulator

The benefits of using an Arduino simulator are here

• Easily separate hardware and software bugs 👢🐛
• develop your code anywhere and test it immediately then and there 😉
• Easy to share the project with others 🧩
• Easy on the pocket 💰
• No hardware necessary
• No need to reuse the components from other projects
• Others can help and contribute in a better way to solve the issues🆘
• Easy to teach online. Anywhere 👩‍🏫
• Carry the simulator in your pocket. Some simulators run on mobile browsers as well 📱

4. What is the best product for learning Arduino Programming?

The best product for learning Arduino programming is an Arduino. Either you can use actual hardware or a free online Arduino simulator. Most importantly, you should give enough time. Start from the simple ones and go to the complex projects.

You can also buy your own Arduino hardware but provided that you are just starting, I would not buy all the interfaces such as Neo-pixel matrices, MAX7219 scrolling displays,

Keep learning and never forget to keep the learning fun 😀

5. Which Simulator is best for Arduino?

It depends. For some, an Arduino simulator is more fun and better when working with it offline. For others, an online-based Arduino Simulator will be preferred. Hence, it finally depends on your preferences. The best Arduino is the one that keeps updating all the time, bugs are fixed soon, and new features are introduced frequently. When we see both Tinkercad and Wokwi Arduino simulators, for example - Wokwi is new, faster, and gets updated all the time. while Tinkercas is old, with no latest updates but has tons of example projects.

6. Is the Arduino Simulator free?

Some of the Arduino Simulators are free and some come with a subscription. Wokwi Arduino simulator is free, and so is the Tinkercad simulator too. Paid simulators are also out there.

7. Can I simulate Arduino Online?

Yes. There are several free Arduino simulators, and a few support online Arduino simulation. You can simulate Arduino online using below Arduino simulators

• Arduino Simulator by Wokwi
• Arduino Simulator by Tinkercad

8. How do I run Arduino Simulator?

To run an Arduino simulator, you have to first build your circuit using the components available in the simulator. Later, write the code in the editor window (in the case of Wokwi) or upload the sketch. You will have a RUN or a play button.

Wokwi Arduino Simulator is the easiest out there to run the Simulation. Open the Simulation, add blink code and press the green button!

Here is the proof 😁

9. Is there any Simulator for ESP32?

Yes. There is a free and online-based ESP32 simulator. You can run both Arduino projects as well as Micropython projects on ESP32 Simulator from Wokwi. ESP32 simulator from Wokwi supports

• ESP32 DevKit v1 - Popular ESP32 development board
• TinyPico - an ESP32 board by UnexpectedMaker

Here is the link to the details of the ESP32 simulator

Arduino Examples running on ESP32 Simulator​

• Blink
• Seven segment counter

FastLED NeoPixel Blink

• APA102 Color Cycles (TinyPico Board)
• WiFi Scanning

MicroPython Examples for ESP32​

• SSD1306 Example
• NeoPixels
• AES256 Encryption
• WiFi Scanning

ESP-IDF Examples for ESP32​

The following examples use the ESP-IDF functions. They are compiled using Arduino ESP32 Core:

• Blink using FreeRTOS API
• Binary LED counter using FreeRTOS tasks
• GPIO button input + interrupts

10. What is Wokwi? What does Wokwi mean?

Wokwi is a free online Arduino and ESP32 simulator. You can use Wokwi to build Arduino projects. Wokwi is a browser-based simulator. Hence, you don't have to install or download anything. Wokwi supports sharing the projects more efficiently.

homepage: https://wokwi.com

Manuals/guides: https://docs.wokwi.com

According to the Wokwi site, Wokwi as such has no meaning. It is only famous for the Arduino simulation support.

11. Does Arduino have a simulator?

Arduino IDE as such doesn't have any simulator built-in. There are several other third-party Arduino simulators out there.

12. How do I simulate Arduino UNO?

To simulate Arduino UNO, click on the Arduino UNO template project

13. How do you simulate Arduino Mega 2560?

To simulate Arduino UNO, click on the Arduino Mega2560 template project.

14. Where can I learn Arduino programming for free?

You can learn Arduino easily. You can learn about Arduino basics from the official website reference link. There are a lot of articles that will guide you through

• Arduino Tutorial 1
• Arduino Tutorial 2
• Arduino Tutorial 3

15. Is Arduino easy to learn?

Yes. getting started with Arduino is easy. There are various free resources and a huge community of users who will support others and help you pick up Arduino programming.

16. How do I teach Arduino online?

Just like any other topic, Arduino can also be taught online. if Arduino is being taught in a classroom (online/offline) environment. Simulators are the best way to go. Arduino simulators won't cost anything. It will be easy to assign tasks as well as review and give feedback on the assignments. Do you know that the Wokwi Arduino simulator is used by several universities to teach Arduino?

17. How do I start learning Arduino Online?

Already answered. in a gist use any of the below resources to get started. You can learn about Arduino basics from the official website reference link. There is a lot of articles that guide you through the learning process.

• Arduino Tutorial 1
• Arduino Tutorial 2
• Arduino Tutorial 3

18. Is there any online Arduino simulator?

Yes. There are several Arduino Simulators. A good list is curated here:

Rest of the answers and More QA coming soon... Please feel free to contribute questions or answers in the comments. I will take them up too in the list

19. How do I simulate Arduino Projects?

To simulate Arduino projects, start with the free Arduino simulators (Wokwi or Tinerkcad). Select the Board you want to simulate. WOkwi supports UNO, Mega, Nano, ATTiny85, Raspberry Pi Pico, ESP32, and More. Tinkercad supports Arduino UNO and more.

The next step is to add the components. You can LEDs, Servo motors, stepper motors, and more. After connecting them in the way you want to, you can complete the Arduino code.

Finally, you have to run the simulation. If you have made any mistakes, an error list will pop up. If not, the simulation should run okay. Here are a few simple simulation projects you can run:

• LiquidCrystal Hello World
• LiquidCrystal I2C Hello World
• LiquidCystal Custom characters
• Electronic Safe
• DS1307 Clock
