Basically, NodeMCU is Lua Interpreter, so it can understand Lua script easily. When we write Lua scripts for NodeMCU and send/upload it to NodeMCU, then they will get executes sequentially. It will not build a binary firmware file of code for NodeMCU to write. It will send Lua script as it is to NodeMCU to get executed.In order to drive the motors we will use the L293D a Quadruple Half-H Drivers H-Bridge. According its Datasheet, The L293 and L293D devices are quadruple high-current half-H drivers.The L293 is designed to provide bidirectional drive currents of up to 1 A at voltages from 4.5 V to 36 V.This code is to blink built-in LEDs of NodeMCU. The on-board LED of ESP8266 is connected to GPIO2 and ths LED on NodeMCU board is connected to GPIO16. Working of this code is same as we explained earlier for external LED blinking with NodeMCU. int LED1 = 2; // Assign LED1 to pin GPIO2.In this tutorial, I will show you how to use the Arduino IDE to program an ESP8266 microcontroller to read sensor data and publish it using MQTT to a HiveMQ Cloud MQTT broker. Further, I’ll show you how to receive MQTT messages as commands from the cloud and activate the microcontroller output to switch ON and OFF a Light Emitting Diode (LED).Here is an illustration of the pinout for the ESP8266 12-E chip. This diagram is useful if you are using a bare ESP8266 chip in your projects. Can be used as a general-purpose I/O pin. It is a multipurpose pin that can be used for various purposes. It also has a built-in pull-up resistor.
