servo tester


Posted on Feb 7, 2014

Built servo tester cicuit as shown - only action is for the servo to twitch when power switched on, cannot see any real reason why wont work - ideas anyone I haven`t built this circuit yet so I can`t comment on the circuits efficacy. I do have some experience of using servos in radio controlled models, both aircraft and cars. Whenever I have experienced servo twitch it has been caused by some form of

interference, not necessarily from your circuit but signals from things like refrigerators and the like when tested indoors and in close proximity. The servo tends to glitch and twitch if their is a fault in the rx. Sometimes the servo itself can be faulty. Try another servo. My bet is that its noise from either external components or maybe the circuit itself. I have had to install ceramic capacitors to small electric motors before now to cut the excess noise that can affect a servo. That`s my best guess, hope it helps or at least points you in the right direction. I haven`t built this circuit yet so I can`t comment on the circuits efficacy.
