This project is a test of using the Arduino Uno R4 WiFi to serve DHT22 sensor data over a simple website based on some modern web tools like TypeScript and Parcel.js. The firmware will read out the ...

Wire up the touch sensor module to the Arduino Uno as per the circuit setup section. Code Upload: Open the Arduino IDE and create a new sketch. Copy and paste the provided Arduino code into the sketch ...

Our Smart Home Using Arduino Uno R4 WiFi project is designed for home safety and convenience, integrating temperature, humidity, light, and gas monitoring. Using sensors like DHT11/DHT22, LDR, and ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

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 ...

The R4 WiFi is already equipped with Wi-Fi communication, thanks to the onboard ESP32-S3 module, which the Rev3 lacks. The R4 WiFi's Wi-Fi feature offers speeds of up to 150 Mbps and can function ...

Arduino UNO R4 (preliminary) specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash. 8KB dataflash; Wireless (Arduino UNO R4 WiFi only) – ESP32-S3-MINI ...

This project used the XBee Pro Module to transmit and receive signals wirelessly, and an Arduino UNO executed all given instructions. The presence of the car was identified by an infrared sensor, also ...

In addition to the same RA4M1 microcontroller as the R4 Minima, the R4 WiFi also boasts an Espressif ESP32-S3 module for WiFi and Bluetooth Low Energy connectivity. There’s also a super-bright 12x8 ...

Now that we mentioned the Arduino UNO R4 WiFi, let’s see in what way it differs from the UNO R4 Minima. First of all, there is, of course, the Wi-Fi & Bluetooth LE module, an ESP32-S3 from Espressif.
