Analog Feedback Servo ID: 1404 DESCRIPTION Page 1 of 2 -
Page 2 of 2 It looks like a servo, it acts like a servo, but it's more than just a servo! We got a factory to custom-make these classic 'standard' sized hobby servos with a twist the feedback (potentiometer wiper) line is brought out to a fourth white wire. You can read this wire with an analog input such as those on an Arduino, to get the servo's position. That information can be used in robotics to improve stability or even allow 'recording' of servo motion.
