MDDN 251: Process of connecting the Lights to the Microcontrollers

I completed the circuit that was posted earlier and here is the outcome:

This circuit only uses half of the LEDs on the display so in order to use the rest, i must connect the overflow of the first microcrontroller to the data of the second microcontroller and complete this circuit here and create a Dual Shift Register:

That process went relatively well and i ended up with all of the lights being able to brighten up. Then with the code provided applied, it made them flash one after another in the sequence that is shown in previous videos. This is great progress on getting the screen to work. Now i must struggle to get the microphone to connect to the screen.
