Wemos D1 mini is like a “little Arduino with WiFi” for a great price. It’s based around the ESP8266, has one analogue port and 11 digital ports. It’s programmed via micro-USB (or remote flash via wifi).
The WeMos D1 Mini is a reasonable ESP8266-based WiFi board that is low-profile however similarly as incredible as any NodeMCU or ESP8266-based microcontroller. The D1 Mini is amazingly flexible in light of the fact that it is economical, WiFi-empowered, and completely viable with the Arduino stage. In this instructional exercise, the ESP8266 library and board chief will be acquainted all together with get the D1 Mini going about as an Arduino board. At that point, a basic page will be presented with the expectation of bridling the WiFi abilities of the module. The D1 Mini will go about as a web worker, permitting any WiFi-associated gadget to communicate with the board and control its pins wirelessly.It can be customized utilizing little exertion, and the Arduino IDE.
