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.

The UNO R3+WiFi (ATmega328P+ESP8266) board is an unofficial Arduino Uno clone, but has Wi-Fi capabilities. It is promising for many do-it-yourself projects because you can use a single board to easily ...

Project Description This system integrates an Arduino Uno with an ESP8266 WiFi module to create a responsive home automation controller. It supports up to four relay-connected devices, allowing users ...

A lot of people have used ESP8266 to add inexpensive WiFi connectivity to their projects, but [Oscar] decided to take it one step further and program an Arduino over WiFi with the ESP8266. [Oscar] … ...

This is a fork of Arduino.org WiFi Link firmware. The goal of this fork is make improvements and provide documentation. The WiFi Link firmware is an ESP8266 arduino sketch developed by Arduino.org in ...

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE. Finall… ...

Arduino UNO R4 WiFi. Arduino UNO R4 specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash; Wireless (Arduino UNO R4 WiFi only) – ESP32-S3-MINI-1 ...

Arduino also upgraded the R4 WiFi's analog-to-digital converter (ADC), which is responsible for reading data from the analog inputs. On the Rev3, the ADC supports up to 10-bit resolution, with ...

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 ...

The Arduino UNO R4 Minima and the Arduino UNO R4 WiFi. But apart from the obvious wireless connectivity hinted by the name what other differences do the microcontrollers have.
