This guide focuses on the 4 digit 7 segment display interfacing with ESP8266 NodeMCU using 74HC595 shift register and Arduino IDE. By using the 74HC595 shift register to drive 7-segment displays with our ESP boards, we can save GPIO pins of ESP8266 NodeMCU. First, we will show you some descriptions of 7 segment displays and … Read more

74HC595 IC is a 16-pin shift register IC consisting of a D-type latch along with a shift register inside the chip. It receives serial input data and then sends out this data through parallel pins. In addition to parallel outputs, it also provides a serial output. It has independent clock inputs for the shift register … Read more
This article is about how to easily and massively expand digital outputs by using the 74HC595N shift register with Arduino Uno or Arduino Mega. Sometimes, in many electrical and embedded systems projects, there is a need to connect and operate more sensors or other output devices to the Arduino. However, there are no more output … Read more
