The Buyer’s Guide

Programming

When it comes to coding the ESP8266, there are numerous approaches. When it comes to programming the ESP8266, the Arduino IDE is widely used. Even for newcomers, it may seem to be more comfortable, and for those who’ve been in it for a while, it may seem to be a piece of cake. There are times when you’ll need to use a little technique to move farther on the Arduino.

In this case, you may want to look into using an official SDK to develop it in actual C. ESP8266 Board, an accessible WIFI network, USB cables, a system or PC that can execute the Arduino IDE, and so on are some of the components needed for programming.

NodeMCU

The firmware for the nodeMCU is based on the ESP8266 WiFi SOC. The nodeMCU refers to the firmware, not the development kits, which employ the Lua programming language. The nodeMCU, like the ESP8266, was invented in December 2013 and is widely used in IoT applications.

Power sources

You may power the ESP8266 WiFi module using 2 AA batteries, a PC serial port if you’ve a TTL-Serial-to-USB adapter (don’t attempt to attach the module to a PC serial port manually, you might harm the module or your computer! ), or a USB port if you have a TTL-Serial-to-USB adapter. The ESP Dev Thing board may be powered using LIPO batteries. The LM117 3.3V regulator may be used.

Pinout

One thing to keep in mind while looking at the ESP8266 pinout is that not all pins are acceptable for use, and certain pins are only used for certain purposes. The nodeMCU is often mistaken for the ESP-12E, although this is incorrect. Unlike the ESP-12E, which relies on the UART for recording, nodeMCU relies on the USB. Use numbers in front of the GPIO while programming (AO, DO, D1, D2, D3, D4, D5, D6, D7, D8). 

Put the oscilloscope near the edge of the pins due to the variation in the nodeMCU pins, that is, some pins are up and some pins are down.  AnalogRead seems to be compatible only with ADC, GPIO 6,7,8, and 11 are not compatible with ADC, digital white is not compatible with ADC.

The logic pins on the microcontroller are all 3.3V, and it’s the most frequent purpose pin. The serial pins, such as the RX and TX pins, are also available. Both are V and 3.3V, however, the RX is the module’s input, whilst the TX is the module’s output5.
