Simulator for Arduino is a comprehensive and advanced simulator for demonstrating the inner workings of an Arduino. It is the most feature-rich software available currently. Its ability to educate through simulation is unmatched.

You can download the free version that offers a short delay timer on loading a sketch. Upgrade to the Pro Version when you're ready. The Simulator for Arduino Pro Version is currently used in many countries worldwide. It offers a zip file of a setup.exe file that installs an exe file, help files, images, and examples, making it easy and quick to use.
The Simulator is designed for the Arduino Uno, Mega, and other popular Arduino boards. It enables you to perform various essential tasks, including stepping through the program line by line, performing digitalWrite, digitalRead, and PinMode for pins 0-53, analogRead for pins 0-16, and analogWrite for digital pins 0-53. Additionally, the tool emulates Serial, LCD output, Ethernet, Servo, SD card, EEPROM, SoftSerial, SPI, and Wire. It provides If, while, for, switch, do while loop functionality, and subroutines (multi-level) with arguments.
Furthermore, the Simulator offers real-time variable viewing, displaying variables in real-time while in Step Into, Step Over, Step Out of or Run mode. It allows you to edit the sketch or open it in Arduino IDE, view tabs for separate files in the sketch, and access context-sensitive help. However, the Simulator only provides support for 2 and 4 line LCD with improvised CGRAM, and it has limited support for custom libraries.
In conclusion, if you're looking for a comprehensive Arduino Simulator with plenty of features and reliable performance, the Simulator for Arduino is an excellent tool to consider. Its advanced features and benefits make it a popular option to develop and debug your Arduino sketches, even before hardware usage.
