NodeMCU DEVKIT V3 (Chinese clone) Client

Read more at NodeMCU Wikipedia Page

Sends GET request to Local Server and displays event data on the LCD at regular intervals.

The Chinese V3 clones are a bit larger than the regular V2 board. But one reserved pin is connected to USB +5V and another to GND in these clones.

Shields:

16x2 LCD I2C LCD (Or I2C LCD Adapter Module)

Libraries:

ArduinoJson
LiquidCrystal_I2C

 

Circuit diagram

Will be added at a later date as no Circuit Design software supports NodeMCU V2 or V3 at this date.

 

Pin Configuration

Very simple as we are using LCD I2C Adapter board. Hence, only 4 female-female jumpers are required.

NodeMCU

Name	Connects to
GND (G)	I2C LCD GND
VUSB (V)	I2C LCD VCC
D1	I2C LCD SCL
D2	I2C LCD SDA

 

Install ESP8266 Platform in Arduino IDE

Starting with 1.6.4, Arduino allows installation of third-party platform packages using Boards Manager. We have packages available for Windows, Mac OS, and Linux (32 and 64 bit).

1. Install Arduino 1.6.8 from the Arduino website.
2. Start Arduino IDE.
3. Open Preferences window by File > Preferences
4. Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
5. Open Boards Manager from Tools > Board > Boards Manager and install ESP8266 platform.

 

Build Instructions

1. Connect pin jumpers to pins.
2. Download libraries from Sketch > Include Library > Manage Libraries
3. Change WiFi SSID and password.
4. Change Local Server IP.
5. Select NodeMCU 1.0 (ESP-12E Module) from Tools > Board
6. Select COM Port from Tools > Port
7. Compile and Run.
8. Open Serial Monitor to read debug logs.
