Someone has invented a way to add Wi-Fi to a standard Arduino Uno, by proposing a module that drops into the DIL socket normally reserved for the ATmega328 – it will not work with Unos that have a ...

The release of the next-generation UNO board by Arduino represents a considerable upgrade to its 8-bit technology. The new UNO R4 is powered by a 32-bit microcontroller and is available in two ...

Connector to add external battery to real-time clock (RTC) inside Renesas MCU (MCU RTC power pad held to 5V rail on Minima) Secondary (wireless) processor: 240MHz 3.3V dual core 32bit Espressif ...

The guys and gals at Arduino have just released the latest and greatest version of the Arduino Uno. The previous generation was called the R3, so it’s no great surprise that the new generation flaunts ...

Simple distance measurement project using an HC-SR04 (or compatible) ultrasonic sensor with the Arduino Uno R4 WiFi board. The sketch reads distance and prints it to the serial monitor.

As we discussed in my previous column, until a few weeks ago, the Arduino Uno microcontroller development board we’ve all grown to know and love was the R3 (“Revision 3”). This little rascal is ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...
