Learn Arduino

Learn Arduino is a web course by Dilum Sanjaya; the credit on the site matches his X account. It has 16 lessons that go from LEDs, buttons and sensors to motors and complete small projects, with component explanations, a simulator and a serial monitor on the page. The author says on X that the site was made with Opus 5.5. You can explore circuits in the browser before you own a board.

Who it's for:Arduino beginners and students in electronics classes.

Before you start: it opens in the browser, the lesson text needs no sign-in, and we saw no payment. The site is in English. The lessons use the Arduino Uno name and board as teaching examples, and the site doesn't explain its relationship to Arduino. Check safety separately before wiring real circuits or power. The site states no reuse licence, and we didn't check the scripts it loads or a privacy policy.
