One million students and enthusiasts bring circuits to life
with EveryCircuit's interactive visual circuit simulation.
Build an arbitraty circuit, and EveryCircuit will show you how it works, even if you have just invented a new design. This is made possible by a custom-built circuit simulation engine under the hood.
Dynamic animations of voltages, currents and charges are displayed right on top of schematic. Detailed visualization gives insight into circuit operation like no equation does!
Adjust circuit parameters while simulation is running, and see how circuit responds, all in real time. Touchscreen interface makes it feel like you are building circuits with your hands.
Simulate examples in class right on your phone or tablet. Animate textbook circuits and understand how they work. Check homework answers.
EveryCircuit user community has collaboratively created
the largest searchable online library of circuit designs.
EveryCircuit runs on Windows, Mac, and Linux in Chrome browser.
There is no need to install or update the web app. The latest version is launched when you visit
apps give you freedom to capture design ideas on the go and follow lectures in class. Intuitive touchscreen interface makes it very easy to build circuits and interact with them.
Your circuits are backed up in the cloud and synced to all your devices across platforms. With cloud storage the circuits are accessible from anywhere.
Community is a place to discover circuits, publish your work, ask questions, and get help with your designs from fellow community members.
circuits, and circuits from top community contributors.
Interactive simulation can be embedded right on your website with a single line of html. Simulation requires non-mobile Chrome browser and takes a minute or two to load for the first time.

destroyed a Toshiba 2SC5570 HOT doing this last night. looking at the simulation, when the output is switched off, the flyback caused a huge negative voltage spike on the collector, pulling current through the base. is that coreect
I copied this circuit diagram from another website. I have copied it almost exactly to create a triangle wave generator. I have been able to create the correct output signal but i noticed the voltage is ranging between 0 and -600mv.
Is this signal still usable in a circuit?
Can I adjust it to create a +voltage signal.
I had to add the 1khz AC voltage source as shake to start feature did not show a correct output. I am just experimenting with these types of circuits to learn more. Any help appreciatted.

You push the switch once for 1 second to close the circuit. After that you open the circuit by the switch. In that short time when the swich was closed the capacitor has been charged and will power the transistor base for a while to keep the emitter collector opened and the LED lightened.
When you close the switch the capacitor will be depleted. When you open the circuit by the switch the capacitor will start to charge. When the charging is completed the transistor base will receive current. The colector emitter will let the charge to pass trought and the LED will light.

555 timer circuit embedded on the right is a very popular integrated circuit that can operate in monostable, bistable, and astable modes.
In astable mode the 555 timer produces a square wave at the output.
Adjust values of the capacitor on the left and two resistors above it and note the effect on output period and duty cycle. Click the minimized oscilloscope in the corner to expand it.
In monostable mode the 555 timer produces a single pulse of a certain duration when the trigger pin is set to low.
Flip the switch twice to trigger the pulse.
Adjust the capacitor on the left and the resistor above it to control the puse duration.
In bistable mode the 555 output can be either in high or low state.
Double-flip the two switches to alternate between the states.
Setting the trigger pin low makes the output go high.
Setting the reset pin low brings the output back to low.
