Wire virtual components, run simulations, and get instant feedback — before touching real hardware.
LED Circuit
Wire an LED safely with a resistor to an Arduino pin.
Motor Control
Connect a motor driver and DC motor to your Arduino.
Sensor Wiring
Wire an ultrasonic sensor so the Arduino can read distance.
Smart Night Light
Use a photoresistor to detect darkness and auto-light an LED.
Interactive Button
Press a push button to toggle an LED on and off.
Variable Dimmer
Turn a potentiometer knob to control LED brightness (PWM).
Distance Alarm
Sound a buzzer when something gets too close to the sensor.
Free Build
No rules — experiment with any combination of components.
