5x NodeMCU WeMos ESP8266 WiFi Lua Board, CH340

This listing is for the WeMos version of the NodeMCU board. 

There are many suppliers of NodeMCU boards, and most of them contain different software. It can be very, very time consuming getting them to work, and figuring our what software they have running on them. There are two main, popular ways to use and program the NodeMCU board:
- Use it with the standard Arduino IDE
- Use it with the official NodeMCU Firmware, and NodeMCU's Lua Interpreter

-- Use NodeMCU with Arduino IDE --

This is a very popular and easy way to use NodeMCU!

For detailed information how to very easily program this board from within the Arduino IDE (V1.6.4 and higher), see this page on our wiki.

After buying this item, we will send you detailed information how to very easily program this board from within the Arduino IDE (V1.6.4 and higher).

For example, to flash the system LED, the following Arduino program can be used:

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

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

--- Use NodeMCU with Lua ---

The official NodeMCU firmware contains the Lua Interpreter. Lua is an interactive programming language which allows you to experiment and build simple working programs without a lot of effort. If you are not familiar with Lua, you will find that it is not hard to learn, at least for the simple tasks needed to get started.

For detailed information how to program this board with the official NodeMCU firmware, see this page on our wiki.

After buying this item, we will send you detailed information how to program the board with the official NodeMCU firmware.

The official NodeMCU site does NOT supply pre built(compiled) firmware. You have to build a custom version using their online compiler. BUT, we have made it easy for you by providing a pre built firmware for the hardware we sell, along with very easy instructions how to program it.
