Only one joint moving
Hello Rongzhong,
I have the issue that only one joint (13) of all joints is moving. The batteries are sufficiently charged and all motors are connected to the NyBoard, and I believe the wiring is correctly (even if it isn't more than one motor should move?). When I try to calibrate the servos no. 13 is the only one that rotates, same goes for when I type in a command.
When I run Nybble.io I always get "FIFO overflow! Using last reading!" in the serial monitor. I also tried different settings on the onboard potentiometer.
Thank you for your time and help!

Have you uploaded writeInstinct.ino first? It has to be uploaded at least for the first time.
The brown wire of all servos should be facing outside. Compare them with joint 13, since it's working right now.
"FIFO overflow! Using last reading!" is not a big problem. It's just a system status report and is dealt with in the algorithm.
