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.\u003c\/p\u003e\n\u003cp\u003eNote that the default servo pulse widths (usually 1ms to 2ms) may not give you a full 180 degrees of motion. In that case, check if you can set your servo controller to custom pulse lengths and try 0.75ms to 2.25ms. You can try shorter\/longer pulses but be aware that if you go too far you could break your servo!\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Feedback-Servo-Record-and-Play\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCheck out this example Arduino sketch which demonstrates how to record motion data to the EEPROM and then play it back when a button is pressed.\u003c\/a\u003e Comes with a range of horns as seen above.\u003c\/p\u003e\n\u003ch2\u003eTechnical Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 11.58mm \/ 0.45\" x 22.75mm \/ 0.89\" x 29.19mm \/ 1.14\"\u003c\/li\u003e\n\u003cli\u003eMax Dimensions: 11.58mm \/ 0.45\" x 32.74mm \/ 1.28\" x 31.19mm \/ 1.22\"\u003c\/li\u003e\n\u003cli\u003eWire length (at least): 131.67mm \/ 5.18\" long\u003c\/li\u003e\n\u003cli\u003eTorque: 25 oz*in \/ 1.8 kg*cm @6V\u003c\/li\u003e\n\u003cli\u003eSpeed: 0.1 sec\/60° @6V\u003c\/li\u003e\n\u003cli\u003eWeight: 15.81 grams\u003c\/li\u003e\n\u003cli\u003eDual ball bearing\u003c\/li\u003e\n\u003cli\u003eMetal gearbox\u003c\/li\u003e\n\u003cli\u003eApprox 120 degrees of rotation (500 to 2500 microseconds)\u003c\/li\u003e\n\u003cli\u003eSpline Count: 22\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":39643554447443,"sku":"ADA1450","price":14.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/1450-00.jpg?v=1642084409","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/analog-feedback-micro-servo-metal-gear","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
