A free, interactive Arduino course that starts from zero. Write real C++ sketches and run them on an Uno-compatible board next to your code: LEDs light, buttons press and the Serial monitor prints. With AI hints and a certificate of completion.
- Write C++ sketches with setup(), loop() and the digital and analog pins
- Read buttons, knobs and sensors, and drive LEDs, servos and buzzers
- Run several timed tasks at once with millis() instead of delay()
- Show readings on displays and build complete projects
