Arduino UNO and ESP8266 are two popular microcontrollers used in DIY electronics and IoT projects. The Arduino UNO is a microcontroller board based on the ATmega328P chip, while the ESP8266 is a WiFi module with an integrated microcontroller.
One of the main advantages of using the ESP8266 with an Arduino UNO is that it allows the Arduino to connect to a WiFi network and communicate over the internet. This makes it possible to create IoT projects that can be controlled and monitored remotely.
