Display LED cu 8 Cifre și Butoane Bazat pe TM1638

Specificații tehnice:

• Chip: TM1638;
• Tensiune de alimentare: 5 V DC;
• 2 afișaje cu LED cu 4 cifre fiecare;
• 8 butoane;
• Interfață de control: 3 pini (STB, CLK, DIO);

The module has 3 control pins, power pin and table. Control pins are strobe, clock, and date. Strobe and clock pins are output pins, and the data pin can be used for both output and input. The strobe pin is used when sending data to the board, setting the strobe on LOW before sending the data, one or more bits, and when sending is done, the strobe pin is set to HIGH. There is only one date pins, so the information can be bit-bitted. The clock pin is used for each bit reference. Set the clock pin to LOW, send a bit, then set the clock pin to HIGH.

A short code of use with Arduino using the LEDs is attached at the bottom of the page. We also attached both the module schema and the TM1638 technical datasheet.
