I wanted to make this led display project ( Digital clock Max 7219 dot matrix Random animation & how to set the time in the RTC module with code - YouTube ) so i bought all the materials needed but it didnt work the led display is flashing in a random fashion and even turn on when the vcc and gnd aren't connected to the display.
