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.

Project Description A secure door lock system using Arduino Uno, RFID (MFRC522), and a 4x4 Matrix Keypad. Authorized users can unlock the door with either an RFID tag or a PIN code.

In this project, I designed and implemented a secure, efficient, and user-friendly door lock system using RFID technology integrated with an Arduino Uno microcontroller. The system automates access ...

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… ...

Details of Arduino UNO R4 32-bit board revealed, including the 12x8 RED LED matrix on board and connectivity for IoT applications.

Now, with a serial bootloader and an ESP8266 in Wifi-to-serial bridge mode, you can reflash your microcontroller wirelessly, and then telnet in to interact with and debug the system remotely.

Arduino Uno R4 WiFi comes with built-in Wi-Fi and Bluetooth capabilities, along with additional pins and a new, faster processor.

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.
