Hi,I am YKSky.

I made a binary clock by arduino nano & tiny rtc.

The right bottom is minute + or -.

The left bottom is hour + or -.

Code & Pin

const int setHup = 17; //button for hour increase

const int setHdown = 16; //button for hour decrease

const int setMup = 20; // button for minute increase

const int setMdown = 21; // button for minute decrease

const int UnitTenHrs01 = 12;

const int UnitTenHrs02 = 11;

const int UnitHrs01 = 10;

const int UnitHrs02 = 9;

const int UnitHrs04 = 8;

const int UnitHrs08 = 7;

const int UnitTenMin01 = 6;

const int UnitTenMin02 = 5;

const int UnitTenMin04 = 4;

const int UnitMin01 = 3;

const int UnitMin02 = 2;

const int UnitMin04 = 14;

const int UnitMin08 = 15;
