7 SEGMENT ARRAY LED & KEY - IC TM1638



SCHEMATIC :



This is a “8-Bit LED 8-Bit Digital Tube 8-Bit Key TM1638”.


The board has 3 control pins plus power and ground.
The control pins are STROBE,CLOCK & DATA.
The strobe and clock pins are only OUTPUT while the data pin can be both OUTPUT and INPUT.

The strobe pin is used when sending data to the board – you set the strobe pin to LOW before you start sending data – one or more bytes – and then set the strobe pin back to HIGH. Note that there is just one data pin which means the data is being sent 1 bit at a time. This is where the clock pin comes into play. When sending data you set the clock pin to LOW then you set the data pin and set the clock pin back to HIGH to commit the bit value
