Key Display For AVR Arduino New 8-Bit Digital LED Tube 8-Bit TM1638 Module

This module for the chip TM1638, set the above three kinds of single chip microcomputer common peripheral circuit, the biggest characteristic is to simply take micro-controller three IO mouth can drive, scanning display and key scan don’t need micro-controller intervention, only need to register to display data related to reading and writing or testing buttons, save MCU resources.
