I have a problem with my led display board I made with 74hc595 and ATmega16. The display is not showing the character properly instead the leds are blinking. I had attached a video link with this post. Please help me.

Hi , you're dealing with high ground currents there , make sure the you have a good thick ground line in addition to what andig recommended. I had the same problem , the voltage drop on the ground line is higher on one side. Connect the ground , common clock and latch line in the middle to minimize the voltage drop.
