CircuitLab

Learn electronics by using examples in PROTO application, and try many components available in our application. You can use resistors, diodes, transistors, and much more. Observe signals on a channel oscilloscope and analyze them with ease. During simulation, you can check voltages, currents and many other variables. Check signals on the multichannel oscilloscope 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.

One animated circuit is worth a thousand equations and diagrams. Animations of voltages, currents, and charges are displayed right on top of the schematic, providing great insight into circuit operation. The real-time circuit simulation engine is custom-built for speed and interactivity. Easy one-click simulation, from simple resistors and logic gates to complex transistor-level oscillators and mixed-signal designs. While the simulation is running, you can flip switches, adjust potentiometers, tune LED current limiting resistors, ramp up input voltages, etc. The circuit will immediately respond to your changes, in real time. Mini-waveforms on top of schematic wires look different for digital and analog signals. Constant analog voltages are shown as numbers, digital wires are color-coded. Any pair of time-domain signals may be plotted in the XY mode. The oscilloscope scale and grid ticks are auto-updated to convenient values as the data changes.
