Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

Pinout diagram Wiring configuration to meet the SPE standard You’ll find rather detailed hardware documentation and instructions to get started with the Arduino UNO R4 WiFi, including wiring and ...

The Uno also has a limited number of pins, making it difficult to work with when the project requires plenty of input and output components. However, these two areas are where the Arduino Mega shines.

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

The Arduino Uno R4, with its enhanced features and capabilities, opens up a realm of new possibilities for hobbyists, educators, and innovators.

Discover or rediscover Arduino, thanks to the new Uno R4! The Uno R3, with its 8-bit ATmega328P processor, has been a long-time favorite. But now, the Uno R4 is here to give a boost to your projects.

Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO connections are in physically similar positions to Uno R3, and IO remains 5V.

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
