Hello,
I have successfully finished the Calibration set up of my Nybble, and have successfully passed the Validation check out by writing "d" and "kbalance" to make sure the calibration is correct, and it is. Thank you for sending a new servo!!
The issue is that when I upload and run the "Nybble", it seems to be running correctly and i get the final ""avdude done. Thank You" message in red, but then the nybble starts making a sound that does not stop. When I tried launching the board, I was getting the numbers that you see in the video. what am I doing wrong can how can I do it correctly? Thank you!
I also had this problem when one of the wires from the battery to the green power in block on the circuit board was loose. It looked OK, but the screw wasn't tight.
The beeping and printed number comes from the voltage checking block.
Besides Mark's suggestion, also check that you have the jumper switch (SW3) between the BATT and V_S.
The sound is due to battery low. Either the throw switch on the battery holder is open, or you need new, freshly charged batteries.
