So I have a project in which I am using 4 Towerpro MG996R servos under fairly High Load (only one at a time for a few seconds)…
I first tested the servos with 4 AA batteries in series which works fine (an example of the circuit I used is attached although the voltage says 4V which is obviously wrong)! The project needs to be run off mains power so i brought a 5 Volt, 3 Amp mains adapter thinking that it would have plenty of power however when i wired it up to just 1 servo it couldn’t handle it (let alone 4)… the servo rotates ok (under no load) but when it gets to its destination it twitches and sometimes it starts its movement is a bit weird as well (the led on the plug also switches off when the servo is moving)… I assume this is because it cant draw enough current/voltage from the plug? What can I do to fix this?
I have looked at adding a capacitor… Would this help? Where should I add it? What value should it be?
I have researched it online and all the posts I have found suggested that replacing the batteries with the adapter should work fine… but it doesn’t
