Control Center Latching Relay

I’M PLANNING ON SHOWING THE ENTIRE PROJECT AND THE CODE. I BUILT A 4 LATCHING RELAY TO MAKE ALL OF THE BUTTONS OPERATE. IN DOING SO THE RESET PIN WASN’T WORKING CORRECTLY. IN THE NEXT VIDEO I’LL DISCUSS THAT…

This is the latching relay part of the project. It took the longest to get working correctly.
