About PROTO

Build, simulate and learn about electronic circuits with PROTO circuit simulator

Are you looking for tools like Multisim, SPICE, LTspice, Proteus, Altium or PhET simulations? That's great! PROTO is an real time electronic circuit simulator which means you are able to setup a circuit with various components and simulate behaviour of the electronic circuit ⚡

During simulation you can check voltages, currents and many other variables. Check signals on multichannel oscilioscope and tune your circuit in real time! Our app can greatly help with your Raspberry Pi, Arduino or ESP32 project. You can also use PROTO as logic circuit simulator and perform digital electronic analysis!

ℹ️ You can report an issue or make component request at Github
