#include <TM1637Display.h>

#define CLK D4
#define DIO D5

TM1637Display displayTime(CLK,DIO);

void setup() {
    displayTime.setBrightness(0xff); //set the diplay to maximum brightness
//    displayTime.setBrightness(0x0a); //not so bright;  // setup a time zone, which is part of the ISO6801 format 

void loop() {
    int h = Time.hour();
    int m = Time.minute();

    segto = 0x80 | displayTime.encodeDigit((value / 100)%10); // And off will be without this 0x80 bit set
    displayTime.setSegments(&segto, 1, 1);
