Title: Servo jitter Post by: skg9021 on May 05, 2014, 03:55:36 PM I have 2 towerpro mg995 servo connected to arduino witth 12v 5A supply.the pwm pulse is coming from arduino using PWMServo library. The circuit is attached . When both of the servo are connected sometimes there is minor jitter in servo. What could be the reason?

Title: Re: Servo jitter Post by: KALYANPRODHAN on June 24, 2014, 10:00:08 AM Look for your LM317 current rating. It cannot deliver sufficient current during loading and servo jitter occurs. As a Adjustable regulator, please increase the supply voltage to 6 volt and then check the performance.
If still jitter occurs, just check with another servo. Either servo or power supply is faulty. If servo found, you can try adjusting the internal preset if any. You may try using an buffer stage in signal line too to figure out the culprit... Waiting for your reply.
