Emulino is described as 'emulator for the Arduino platform by Greg Hewgill, originally found on emulino: arduino cpu emulator'. There are more than 10 alternatives to Emulino for a variety of platforms, including Linux, Windows, Mac, Online / Web-based and Chrome OS. The best alternative is Circuit Simulator, which is both free and Open Source. Other great apps like Emulino are Autodesk Tinkercad (Free Personal), QUCS (Free, Open Source), LTspice (Free) and Xcos (Free, Open Source).
Tinkercad is a super easy-to-use, browser based 3D design tool. With Tinkercad you can create 3D printable items: toys to play with, decoration to light up your home or jewelry to express yourself. You dream it, you can make it!
The Quite Universal Circuit Simulator (QUCS) is an integrated circuit simulator allowing the simulation and graphical presentation of results of large-signal, small-signal and noise behavior in circuits.
KTechLab is an IDE for microcontrollers and electronics. It supports circuit simulation, program development for microcontrollers and simulating the programmed microcontroller together with its application circuit.
SimulIDE is a simple real time electronic circuit simulator. It's intended for general purpose electronics and microcontroller simulation, supporting PIC and AVR. PIC simulation is provided by gpsim and avr simulation by simavr.
It is a circuit simulator on a virtual breadboard. it supports virtual components like microcontrollers, TTL, graphical and alphanumerical LCDs and others in addition to virtual instruments and certainly the basic components (resistors, capacitors..).
MyOpenLab is a platform for finished elements (program components) that can be linked together. You can also MyOpenLab with a house builder compare the building blocks used to build his house. The modules often create others.
