CIRCUIT BOX is GyanBox's online circuit lab for students and teachers. Drag realistic components onto a virtual breadboard, connect them with wires, and press Start Simulation to see your circuit come alive β LEDs glow, motors spin, buzzers sound and sensors respond, just like the real thing. No installation, no kit to buy, and nothing to burn out.
π Realistic components β LEDs, resistors, batteries, transistors, 555 timer, relays, motors, water pump, laser and more, drawn to look like the real parts.
β‘ Live simulation β see current flow, LED brightness, motor speed and sensor readings change as you adjust your circuit.
π§ͺ Real sensors β light sensor (LDR), IR obstacle sensor, soil moisture sensor; change light or moisture and watch the circuit react.
π§± Virtual breadboard β mount components just like on a real breadboard.
β
Circuit check β finds wiring mistakes such as short circuits, missing resistors and wrong polarity, and explains how to fix them.
π Save and share β save your projects online and export diagrams as PDF or image for assignments and notes.
