Hello everyone, I need a little hand, I have enough problems with the calibration of the potentiometer of the servos, the motors are left trembling and do not do if normal rotation, moving it by hand seems to be better, but I can not establish the central point, they are servos of 20kg and 220 degrees of torque. I do not know exactly what to do please thank all the possible opinions or if it is better to use the myrobotlab to configure the servos (I am testing it with arduino) thanks
I think you have a power issue, if you use the NervoBoard it will solve that.
1- Make sure your Arduino is grounded to the servo AND to the power source(battery) http://inmoov.fr/wp-content/uploads/2013/12/ArduinoPowerSupply1-1024×771.png
2- Make sure you have enough Amps to supply all your servos.
3- If you are using a breedboard for to power our servos, it might give this kind of jitter problems, because the Amps cannot flow.
