At sometime or another you may run out of pins on your Arduino board and need to extend it with shift registers.  With this shift out module which is based on 74HC595. The datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state." In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller. You can link multiple registers together to extend your output even more. It can also be applies to 51, AVR, PIC and other microcontroller.

 

It is ideal to work together with Interface Shield for Arduino.

SPECIFICATION

  • Voltage: 5V
  • Input Interface: IDC6
  • Output Interface: IDC6
  • Module Size: 41 × 22mm (1.6 x 0.9in)

Jargon buster

Plain-language definitions for the technical terms used above.

AVR
AVR is a family of 8-bit microcontrollers used in many classic Arduino-style boards. If a USB host library mentions AVR support, it suggests the examples or compatibility may be aimed at those older microcontroller boards.
microcontroller
A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
Shield
An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
