You can do it all day long, but if you don’t tell me, I have no idea of the outcome.
So there is very little left to suspect here. Try clicking all=1500 and move the servo to different I/O pins.
Can you get a volt meter to check for 6vdc on the servo bus? Just because the power pack is able to light the LED, it may not be able to power a servo if it was damaged by having the output shorted.
If they were not actively trying to solve the problem… a whole bunch of jokes about the using the force (ie EMF) come to mind…
perhaps later when they have figured it out.
I was using the process of elimination to solve the problem as I do not have a DVM. the LED came on when I placed the VL-VS jumper in and disconnected th e9v battery which means that power is flowing, but did not get the servos to move. So now the only way to know if either the servos are bad or the ps isn’t good enough is to use a DVM on the servo pins.
if the led stays on continuously when you are sending serial commands then the commands are not making it to the controller IC. the light comes on initially but once serial commands start coming in it blinks as each character(?) is received.
