Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led - the green one on the left in the photo.

Shift-out: again? Yes, shift-out registers again, now daisy-chained! But let me write down a short foreword. As probably occurs for most of the subjects, especially those related to the Arduino board, ...

– RAM: 3bytes WS2812B & Arduino Earlier we controlled LED matrixes, strips and other complex LED projects bundled with countless interconnected wires with the help of multiplexers and shift registers.

The best/worst Arduino creation was an open-source Homeland Security non-lethal weapon project: “ THE BEDAZZLER: A Do-it-yourself Handheld LED-Incapacitator”.

Driving an LED and making it flash is probably the first project that most people will have attempted when learning about microprocessor control of hardware. The Arduino and similar boards have an … ...

He ended up designing an 8 by 16 grid of LED’s that was turned into a game of Tetris. He arranged all 128 LED’s into the grid on a piece of perfboard.

The vertsatile Uno Rev3 is capable of more than just a board for experimental and education projects ...

Amongst a flurry of announcements at Maker Faire Bay Area, Arduino has introduced an easy-to-use FPGA board and a re-boot of Uno Wi-Fi, using a new ATmega processor.

If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.
