Keep this manual for future reference.

What is Arduino®

Arduino®
is an open-source prototyping platform based on easy-to-use hardware and software.
Arduino® boards are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino® software IDE (based on Processing). Additional shields/modules/components are required for reading a twitter message or publishing online. Surf to www.arduino.cc for more information.

Overview

WPB107

The NodeMcu is an open-source firmware and development kit that helps you to prototype your IOT product within a few Lua script lines.

chipset………………………………………………………………………………………………… ESP8266
general purpose IO…………………………………………………………………………………..GPIO 10
operating voltage ……………………………………………………………………………………. 3.3 VDC
dimensions ………………………………………………………………………………..5.8 x 3.2 x 1.2 cm
weight ……………………………………………………………………………………………………… 12 g

WARNING

The ESP8266 module requires a power supply of 3.3 V. However, as the WPB107 contains a 3.3 V regulator, it can be connected by using the 5 V Micro-USB or the 5 V VIN pin of the board.
The I/O pins of the WPB107 communicate with 3.3 V only. They do not tolerate 5 V. If interfacing with 5 V I/O pins is needed, we recommend using our VMA410 level shifter.

Pin Layout

Installing the WPB107

Download and install the latest Arduino® IDE on https://www.arduino.cc/en/Main/Software.
Start the Arduino® IDE and open the preference window (File → Preferences).
Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json in the Additional Boards Manager URL’s field.
Close and re-start the Arduino® IDE.
Open the Boards Manager and select the “NodeMCU 1.0(ESP-12E Module)”.

Open the Boards Manager again and install the ESP8266 software.

Restart the Arduino® IDE again.
Connect your WPB107 by using the micro USB and select the communications port of your computer.

Wiring and Software for the Blink Example

Connect an LED to your WPB107. A resistor is not needed as the I/O’s of the WPB107 are current-limited.
The LED can be replaced by for example the VMA331 so a relay can be controlled.

The sketch for this Blink example is integrated in the ESP8266 board information, which you already installed in the Arduino® IDE.
In your Arduino® IDE, open the examples and select ESP8266 and the example Blink.

Now, the following code is loaded in your IDE. Please take note that the WPB107 has no onboard LED.
Compile and send the code to your WPB107, and enjoy the flashing LED!

/ CODE BEGIN
Blink the blue LED on the ESP-01 module
This example code is in the public domain
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 active 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)}
