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.

Let’s see how it stacks up to the Uno, and find out what each of the components on the board do. At the end of the video, I go through the initial set up in the Arduino IDE and run a simple sketch.

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

Two new variants of the Arduino Uno development board, the lightweight Uno R4 Minima and the full-fledged Uno R4 WiFi, are each powered by a 32-bit microcontroller. These next-generation Uno boards ...

At the time of this writing, a number of Arduino boards exist: Arduino UNO, Nano, Mega, Mini, Pro and others (see Resources for a complete list). The Arduino UNO (Figure 1) is the latest version of ...

This post discusses how I integrated a regular microphone into an Arduino setup for some serious audio experiments. I used a prewired module which holds a MAX9814 single chip microphone amplifier with ...

Arduino, the world's leading open-source hardware and software platform, today announced the launch of its next-generation UNO board, a significant re ...

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 ...

One of the most significant differences between the classic Rev3 and Uno's more recent iteration, the R4 WiFi, is the microcontroller. This component is the brain of the board and is what gives ...

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.
