Description
This is a demo version for Droid Tesla Pro!
Droid Tesla is a simple and powerful circuit simulator.
Perfect for students new to electronics circuit design and construction, hobbyist and tinkerers and even seasoned professionals who want a quick, handy tool to perform electronics circuit design calculations.
That's interactivity and innovation you can't find in best SPICE tools for PC like Multisim, LTspice, OrCad or PSpice (trademarks belong to their respective owners).
DroidTesla simulator solves basic resistive circuits using Kirchoff’s Current Law (KCL) in much the same way a student in a circuits class would,the simulator systematically forms a matrix in accordance with KCL and then proceeds to solve for the unknown quantities using various algebraic techniques such as Gaussian elimination and sparse matrix techniques.
For non-linear components, such as the diode and BJT ,DroidTesla engine searching for the approximate solution by making an initial guess at an answer and then improving the solution with successive calculations built upon this guess. This is called an iterative process.DroidTesla simulation uses the Newton-Raphson iterative algorithm to solve circuits with non-linear I/V relationships.
For reactive elements(capacitors and inductors),the DroidTesla uses numeric integration methods to approximate the state of the reactive elements as a function of time. DroidTesla offers the Trapezoidal(I'll add a GEAR method later) integration methods to approximate the state of the reactive elements. Although for most circuits, both methods will provide almost identical results, it is generally regarded that the Gear method is more stable, but trapezoidal method is faster and more accurate.
DroidTesla for now can simulate: -Resistor -Capacitor -Inductor -Potentiometer (available only in pro version) -Light Bulb (available only in pro version) -Ideal operational amplifier -Bipolar junction transistor (NPN PNP) -MOSFET N-channel depletion -MOSFET N-channel enhancement -MOSFET P-channel depletion -MOSFET P-channel enhancement -JFET N and P (available only in pro version) -PN Diode -PN Led diode -PN Zener diode -AC current source -DC current source -AC voltage source -DC voltage(battery) source -CCVS - current controlled voltage source -CCCS - current controlled current source -VCVS - voltage controlled voltage source -VCCS - voltage controlled current source -Square wave voltage source (available only in pro version) -Triangle wave voltage source (available only in pro version) -AC ampermeter -DC ampermeter -AC voltmeter -DC voltmeter -Two channe oscilloscope (available only in pro version) -SPST Switch (available only in pro version) -SPDT Switch (available only in pro version) -Voltage controlled switch (available only in pro version) -Current controlled switch (available only in pro version) -AND (available only in pro version) -NAND (available only in pro version) -OR (available only in pro version) -NOR (available only in pro version) -NOT (available only in pro version) -XOR (available only in pro version) -XNOR (available only in pro version) -JK flip-flop (available only in pro version) -7 Segment Display (available only in pro version) -IC 555 (available only in pro version) -Transformer (available only in pro version) -Graetz Circuit(available only in pro version)
If you are making an oscillators you have to put a small initial value on some of the reactive elements.(see the examples)

★★★★★Alejandro Calderon· Oct 10, 2025
I love this app, make me enter the world of electronics... love that I can move the wires and the components, but you can make a little friendly, like to modify the values of resistance and that stuff, without stop the simulation, and add more components !!!

I've been using the app for years now. This is a must-have for quick throw together for proof, fault-finding or to better understand a circuit. Make you own chips by combining and combining. Marking pins ya a little slow. After that huge circuits can be achieved in less time than what your thinking right now. Way less. No joke. One Problem... I should take off a star, but I'm not ((this software is a masterpiece))) THE PRobLEm is I can not save Offline. It uses to.

Update Droid Tesla Circuit Simulator Full Version. Please 🙏🙏🙏

I have the Droid Tesla Pro app. Well I can say it's a good application on its own, and helped me to understand a lot of basic things. But. The reason I put that low rating is that some components does not work as expected. For example the wave generators. When you put 1Hz, it doesn't work as expected. The Schmitt circuit with transistors or any other components like op amp, doesn't work as expected. The mosfets does not work as expected, the flip-flops does not work as expected. Rest on email

What is risky in your application as Google cautions me on installation. You will be liable for any problem caused by your application. After all why should play store allow risky applications.
