In this tutorial we interface 16×2 LCD display with ESP8266 NodeMCU without using I2C and with minimum pins i.e. using only 3 pins. To interface LCD with ESP8266 we need at least 6 IO lines but ESP already have very few IO lines, to expand IO lines we use serial to parallel shift register IC 74HC595.
