Real-Time Analog & Digital Simulation

Simulate circuits with voltmeter, ammeter, oscilloscope, and logic analyzer. Observe current, voltage, signals transitions in real time

Microcontroller Simulation- AVR, PIC, 8051 & Arduino

Write, compile, and run code on microcontroller cores. Connect sensors, displays, and modules to build complete embedded projects.

Built-in Code Editor & GDB Debugger

Set breakpoints, inspect registers, memory and assembly code and debug like it's real hardware. (current support- AVR & Arduino)

9,000+ Arduino Libraries. Inbuilt Support.

Every library on arduinolibraries.info works natively in EWsim — no installs, no setup
