For everyone who's interested in a Arduino Simulator: I'm Louis and I am 18 years old, I made my own Arduino Simulator a few years ago. the simulator can very easily simulate your projects.

Thanks to the ArduinoSim library, the simulator has the possibility to simulate your codes by only changing one letter in the instruction: digitalWrite becomes DigitalWrite.

Only connect the Arduino board to the computer and upload the sketch, then select the digital/analog pins you will simulate and connect with the simulator. It's also possible to use simulated components with real hardware components together. I want to share this with all of you! Available for MacOS and Windows fully free, donation are very welcome.

Features

The Arduino Simulator has many components built in. Simply drag the parts into the worksheet.
We will add more parts to it within the next updates.
Some sensors can be simulated with a slider,...
