Learn Ohmforge step by step.

1. Your first circuit in 5 minutesLight an LED through a series resistor, power the circuit on, read the current on the multimeter and see what happens when the resistor is too small.Beginner 5 min
2. Oscilloscope & function generatorDrive an RC low-pass filter with a square wave and a sine, measure the time constant and the corner frequency on the 4-channel oscilloscope.Beginner 10 min
3. Bode plots and filtersSweep a filter and an amplifier with the Bode plotter, read the −3 dB corner, phase and unity-gain frequency, and see how gain-bandwidth limits an op-amp.Intermediate 12 min
4. Transistors, op-amps and the 555Switch an LED with an NPN transistor, build inverting and non-inverting amplifiers, and make a 555 blink. Each one is checked against the textbook formula.Intermediate 15 min
5. SPICE netlists, export and convergence troubleshootingImport a SPICE netlist, export a schematic to ngspice or LTspice, and read Ohmforge's plain-language diagnostics when a circuit has no solution or will not converge.Advanced 15 min
6. Automate with the API & MCPRun Ohmforge's simulator from scripts and AI agents. Real HTTP requests and responses for the operating point, transient, AC sweep and LED resistor tools, plus an MCP tools/call.Advanced 12 min
