NEED TO DELIVER A COMPLETE PCB FULLY TESTED

The main issue is the synchronization. It needs to be sync that all LEDs work simultaneously when the Master sends a signal to the Slave saying the function that needs to be performed. I have not tried the other functions like 2 fade color, rainbow, etc. Because blinking is not working properly as it should. If you could try them out, please. For example: when press '4' in the Tera termi...
