LoLin NodeMCU ESP8266 – Quick Start Guide

1. Connect the Board

• Use a USB cable to connect the NodeMCU to your computer.

2. Arduino IDE Setup

• Open Arduino IDE and go to File → Preferences.
• Add this URL to Additional Boards Manager URLs: http://arduino.esp8266.com/stable/package_esp8266com_index.json
• Go to Tools → Board → Boards Manager, search for “ESP8266”, and install “ESP8266 by ESP8266 Community”.
• Select your board: Tools → Board → NodeMCU 1.0 (ESP-12E Module).
• Select the correct COM port: Tools → Port.

3. Test with Blink Example

• Open File → Examples → 01.Basics → Blink.
• Change LED pin if necessary (usually D4 / GPIO2).
• Click Upload and wait for “Done uploading”.
• Observe the onboard LED blinking.

4. Example Blink Code

#define LED_BUILTIN 2  // NodeMCU onboard LED
void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);
  delay(500);
  digitalWrite(LED_BUILTIN, LOW);
  delay(500);
}

5. Next Steps

• Use Serial Monitor (Tools → Serial Monitor) at 115200 baud for debug messages.
• Try WiFi examples: connect to a network, print IP address, build a simple web server.
• Explore GPIO, I²C, SPI, and sensors with the NodeMCU board’s built-in WiFi.
