PROTO - circuit simulator 1.35.1

If you are in search of tools like Multisim, SPICE, LTspice, Proteus, or Altium, PROTO is an exceptional real-time electronic circuit simulator that offers a wide range of features and capabilities. With PROTO, you have the ability to set up circuits with various components and simulate their behavior.

During the simulation process, you can easily monitor voltages, currents, and other variables. PROTO also provides a multi-channel oscilloscope feature that allows you to analyze signals and fine-tune your circuit in real-time. Additionally, PROTO can be utilized as a logic circuit simulator, enabling digital electronic analysis.

Some notable features of PROTO include:

• Animations of voltage values and current flows
• Adjustment of circuit parameters such as voltage, current, etc.
• A four-channel oscilloscope for signal monitoring
• A single play/pause button for simulation control
• The ability to copy electronic components within a circuit
• Access to examples of electronic circuits within the app for learning purposes
• The option to share circuits with friends
• A choice of different themes including Dark, Light, Ocean, and Solarized
• The ability to export circuits as PNG, JPG, or PDF files

PROTO provides an extensive range of components to be used within circuits:

• Voltage sources such as DC, AC, Square, Triangle, Sawtooth, Pulse, and Noise
