Pay attention to these 3 lines: you would need to fill them. Thusopt foryour device fromchoices. After connecting to your ESP8266's AP network, load up a browser and point it to 192.168.4.1/read (unfortunately, mDNS doesn't work in AP mode). ESP8266_Lib.h: No such file or director. You can go with a simple Notepad/gcc setup, fine-tune an Eclipse environment, or use a virtual machine provided by Espressif. They should immediately work on the ESP8266 without uploading any new firmware. So the positive leg of the LED will connected to digital pin to the nodemcu & the Gnd pin of LED will be connected to Gnd of Nodemcu.So 4 LEDs are connected to D0,D1,D2 & D3 pin of Nodemcu. As with any other Arduino, the pin mappings printed on the board match the pin you read or write to. However, from there I tried to setup a quickstart device on the blynk app and that's where I am stuck. The SCL pin also serves as the clock (SCLK) for the ESP8266's SPI interface. Then, towards the bottom of the window, paste this URL into the "Additional Board Manager URLs" text box: You can add multiple URLs by clicking the window icon, and pasting in one URL per line.
