IoT Tutorial #9 [ NodeMCU Tutorials #1 ]
Here I will demonstrate, How to configure Arduino IDE to work with NodeMCU 1.0 ESP8266 (ESP-12E Module).

Problem Statement:

1. To Configure Arduino IDE and install required drivers and libraries to connect NodeMCU to it.

2. Burn First simple program to Blink built-in LED of the NodeMCU board.








Requirements:
- NodeMCU board - 1.0 ESP8266 (ESP-12E Module)
- Micro USB Cable
- Arduino IDE installed on your PC.
- Active Internet Connection


Program Outcome:

Built-In LED (Blue in my case) will blink with specific time interval.
Physical Connection:
Just Connect NodeMCU Board to PC using USB to Micro-USB cable
Steps:
Configure Arduino IDE to connect with NodeMCU 1.0 ESP8266 (ESP-12E Module).

1. Open Arduino IDE
Go To File > Preferances > Put following URL to "Additional Board Manager URL's"
http://arduino.esp8266.com/stable/package_esp8266com_index.json
Click OK.

2. Go To Tools > Board > Boards Manager > Search: Node
Click on "esp8266"
select version 2.3.0 > Click on Install

3. Go to Following Link and Install respective Drivers
https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
4. Go to System Preferences > Security & Privacy > General > Allow
5. Restart Computer
6. Disconnect all connected Arduino Boards
7. Connect NodeMCU to Laptop through MicroUSB cable
8. Open Arduino IDE,
Go To Tools > select Board: "NodeMCU 1.0 (ESP-12E Module)"
9. Go To File > Examples > ESP8266 > Blink
10. Upload the Code
11. Done. Blue LED should Blink on ModeMCU Board With delay of 1 Sec.
12. Now NodeMCU is configured with your Arduino IDE.

Program:
In case you couldn't find the code in File > Examples, Copy below code:
 
/*****************************************************************************
The blue LED on the ESP-01 module is connected to GPIO1
(which is also the TXD pin; so we cannot use Serial.print() at the same time)

Note that this sketch uses LED_BUILTIN to find the pin with the internal LED
*****************************************************************************/

void setup() {
pinMode(LED_BUILTIN, OUTPUT); // Initialize the LED_BUILTIN pin as an output
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, LOW); // Turn the LED on (Note that LOW is the voltage level
// but actually the LED is on; this is because
// it is acive low on the ESP-01)
delay(1000); // Wait for a second
digitalWrite(LED_BUILTIN, HIGH); // Turn the LED off by making the voltage HIGH
delay(2000); // Wait for two seconds (to demonstrate the active low LED)
}

  1. Regarding "#9 NodeMCU: Connect to Arduino IDE and Upload LED Blinking program"

    Thank you for your detailed and complete guide - Well done. However; I still cannot get the serial port to be recognized by the Arduino IDE.
    System: Running MACOS 10.13.06 on a MacBook Pro (13-inch, 2016, Two Thunderbolt 3 ports).

    The SiLabsUSBDriverDisk.dmg reported successful install. Also tried the legacy version of the driver.

    restarted MAC et.al. All installs in Arduino IDE and MAC completed normally and indicated success, however; the Arduino => tools => port dosen't show the serial connection.
    Your thoughts are greatly appreciated,
    Tanks DB

  2. I have the exact same issue. Has anyone got it working yet on a MacBook? Any assistance would be great. Thanks. Paul.

    1. I have done it on Macbook Air only. You can check the video above (that is recorded on Macbook only)
