Description

With PROTO MOD APK, you can build electronic circuits and observe their simulated behaviour in real time. It visualises current flow, lets you change component values while a circuit runs, and supports both basic exercises and digital logic designs.

Real-time circuit simulation

PROTO MOD APK calculates circuit behaviour as you work, so you can follow changes without stopping the simulation. Animated current flow shows the direction of current through the circuit.

  • The four-channel oscilloscope lets you monitor several signals at the same time.
  • The oscilloscope can display signal shapes including sine waves and sawtooth waves.
  • You can adjust a component value during a running simulation and immediately view the circuit response.

Digital logic components

The component library includes logic gates and Flip-flops for building digital systems. You can use these parts for designs such as counters and seven-segment decoders.

  • The available logic gates include NAND and NOR gates.
  • PROTO MOD APK supports 7400 TTL and 4000 CMOS chip families.
  • Version 1.52.0 adds the 4518 dual BCD counter and the 4520 dual 4-bit binary counter.

Phone sensor inputs

You can use your phone's light sensor, accelerometer, and gyroscope as inputs for an electronic circuit. This connects circuit behaviour to readings from the device sensors.

JavaScript and Script ICs

PROTO MOD APK supports JavaScript code for controlling custom ICs. The current release also adds a Script IC with 32 inputs and 32 outputs.

Recent changes

  • PROTO MOD APK is now available in French.
  • This release includes bug fixes and stability improvements.

Requirements

PROTO MOD APK requires Android 7.0 or later. The listed download size is 16.8 MB.

Mod Review

PROTO MOD APK suits people building circuits who want to watch current direction, inspect waveforms, or test logic counters. It also fits users who need a Script IC with 32 inputs and 32 outputs for more involved circuit work. It is less suitable for anyone uncomfortable with an app collecting interaction data, crash logs, diagnostics, device identifiers, and purchase history.

What you get

This listing carries the Premium Unlocked MOD designation. The designation distinguishes this build from the free Google Play listing. PROTO MOD APK's real-time simulation, oscilloscope, logic components, sensor inputs, and JavaScript support remain the core product functions.

Highlights

  • Animated current flow makes it easier to follow the path and direction of electricity through a circuit.
  • A four-channel oscilloscope lets you compare several circuit signals, including sine and sawtooth waveforms, in one workspace.
  • Live parameter adjustments show the effect of a changed component value without stopping the active simulation.
  • Phone light, acceleration, and gyroscope sensors can act as inputs for device-responsive circuit experiments.

Things to know

  • PROTO MOD APK collects app interactions, crash logs, diagnostics, device or other IDs, and purchase history.
  • Android 7.0 or later is the listed minimum installation requirement, and the download is listed at 16.8 MB.
  • Future updates may affect MOD compatibility, especially as version 1.52.0 adds logic ICs and a Script IC.

Should you install it?

Install this build when real-time circuit testing, digital logic parts, and sensor-based inputs match your work. Confirm that Android 7.0 or later is available on your device before downloading.

FAQ

How does the four-channel oscilloscope work in PROTO?

PROTO includes an oscilloscope with four channels, allowing several signals to be monitored at the same time. It can display waveforms such as sine waves and sawtooth waves while the circuit simulation runs.

What has been changed in this Premium Unlocked build of PROTO?

This build carries the Premium Unlocked designation. PROTO remains a real-time circuit simulator with component libraries, oscilloscope monitoring, phone sensor inputs, and JavaScript support.

Which phone sensors can PROTO use as circuit inputs?

PROTO can use the phone's light sensor, accelerometer, and gyroscope as circuit inputs. These sensor readings can be connected to the behaviour of an electronic circuit.

What was added in PROTO version 1.52.0?

Version 1.52.0 adds the 4518 dual BCD counter and the 4520 dual 4-bit binary counter. It also adds a Script IC with 32 inputs and 32 outputs, French language availability, and stability fixes.

What Android version does PROTO require?

PROTO requires Android 7.0 or later as its minimum installation version. The listed download size is 16.8 MB.
