After completed above oprations, try to upload the first sketch to the NodeMCU.
Connect your NodeMCU to the PC and put below code to your Arduino IDE (you can download the sketch file from https://osoyoo.com/download/code/nodemcu-lesson2.zip).
void setup() { Serial.begin(115200);//Set the baudrate to 115200,same as the software settings } void loop() { Serial.println("Hello World!");//Print character string“Hello World!”on the serial delay(5000);// Delay 5 second }
Choose corresponding board/port for your project,upload the sketch to the board.
