Servo PCB Daisy Chaining Working

I plugged in the JST VH and JST 1.25mm wires into the PCBs, and they seem to work!

I adjusted the message struct to hold a desired PCB sort of address or ID. When the MCU detects that the ID matches the PCB (by using the solder jumpers at the bottom of each PCB to program the PCB ID), only then it lights up the LED and replies to the main board.

The mainboard now loops through IDs and sends a message and waits for a response.
