Electronics & Arduino
Build real circuits on a simulated Arduino Uno R3 — breadboard, resistors, LEDs, buttons, motors and an H-bridge. Each level pairs wiring diagrams (which lead goes to which port, and why) with sketches you write and run in the in-browser simulator.
Arduino
Meet the Uno R3 and the breadboard. Light LEDs, size a resistor with Ohm’s law, and read a push-button — building real circuits in the simulator.
Arduino
Go beyond on/off. Use PWM to dim LEDs, read a potentiometer with analogRead, scale values with map(), build a button toggle, and play tones on a buzzer — all on the simulated Uno R3.
Arduino
A microcontroller pin can't drive a DC motor directly — too much current and dangerous back-EMF. Learn to use an L298N H-bridge driver: set direction with IN1/IN2, control speed with PWM on ENA, read a potentiometer to vary speed, and report telemetry over Serial.
Arduino
Build a complete embedded motor controller: a potentiometer sets fan speed via PWM, a push-button toggles direction through an H-bridge, a status LED shows running state, and Serial streams live telemetry — all without a single blocking delay().
