Arduino Uno R4 WIFI Wiring The Arduino Uno R4 WIFI provides one I2C bus on the pin header, which has no pull-ups on the board. Thus, we need to connect a pull up resistor between SDA and VDD and SCL ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — ...

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.

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 ...

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.

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 ...

When you poke around online forums, many people will tell you that the Uno Rev3 is the best Arduino board for beginners, and for good reason. This classic product is one of the most basic boards ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52.

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 ...
