Circuit Simulator

Using this circuit simulator you can effectively simulate most of the basic and standard electronic circuit configurations and modules.

You can simulate many different circuits configurations, such as 555 circuits, 741 circuits, oscillator circuits, comparator circuits, all passive/active circuits, then watch the waveforms on the built--in oscilloscope, track voltage/current everything you want to test with a given circuit design, before venturing into a practical prototype designing.

Please wait for 5 to 10 seconds for the simulator to load.......

hello i hope you are doing well i need help with my project of sound activated switch circuit using 2 op amps this are the componets that are allowed Op-amps: 741, 358, or 324 ,555 timers ,
Transistors, LEDs, relays ,Resistors, capacitors, wires ,we need to double clap to turn on the led and double clap to turn off ,please i need help with the schematic

Standard electronic components

I have tried building the circuit with multism and theres ni mic and relay
Any suggestions which software to use

I think it is better to build it practically and then tweak the settings slowly to achieve the intended results…
I have no idea which simulator would be the best to test these circuits…
