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 correct board to NodeMCU 1.0 and select correct port as per lesson 1 instruction.
After upload the sketch code, click Serial Monitor button, you will see the running result as below:
You will see the serial monitor output every 5 second.
Note: Make sure the baud rate is same as your sketch setting.
