Download SimulIDE – Real-Time Electronics Circuit Simulator with Arduino Support

SimulIDE is a free, open-source real-time electronic circuit simulator that doubles as an integrated development environment (IDE) for programming microcontrollers. It allows students, hobbyists, and engineers to design, simulate, and test electronic circuits — including those with Arduino, AVR, PIC, and other microcontroller boards — without needing physical hardware.

The simulator provides a rich component library covering resistors, capacitors, transistors, LEDs, LCD displays, logic gates, sensors, and a wide range of microcontroller boards. Its built-in code editor supports C and assembly, with real-time simulation that lets you watch your code interact with the virtual circuit as it executes.

SimulIDE is ideal for electronics education, rapid prototyping, and debugging microcontroller firmware before deployment on real hardware. It runs on Windows, Linux, and macOS, and is regularly updated with new components and improvements by its active development community.
