{"title":"Analog Feedback Standard-Size Servo","handle":"analog-feedback-standard-size-servo","url":"/products/analog-feedback-standard-size-servo","description":"This standard-size hobby servo adds a handy fourth white wire that brings out the internal potentiometer wiper. Connect it to an analogue input on a board such as an Arduino to read the servo’s position as a voltage while still driving the servo as normal.That feedback signal can be useful in robotics projects where you want better stability, position monitoring, or the ability to record and replay servo motion. The included example Arduino sketch demonstrates recording motion data to EEPROM and playing it back when a button is pressed.Default servo pulse widths, usually 1ms to 2ms, may not provide the full 180 degrees of movement. If your servo controller supports custom pulse lengths, try 0.75ms to 2.25ms; going too far beyond the servo’s range could damage it.As of January 29, 2024, this servo uses digital internal control circuitry. The feedback signal remains an analogue voltage and works the same as the previous version. It comes with a range of horns.Specifications:Shell: High Strength nylon fiber shellGear: High Strength nylon gearControl circuit: Integrated digital control circuitBearing: Dual-ball bearingDimensions: 39.3mm x 19.4mm x 38.7mmWeight: 48.8gParameter: 4.8V-3.8kg/cm - 0.22sec/60degreeParameter: 6V-5.0kg/cm - 0.18sec/60degree","vendor":"Adafruit","product_type":"Servo Motor","in_stock":true,"options":[],"variants":[{"id":16349,"title":"Default Title","sku":"AF-1404","mpn":"ADA1404","price":33.95,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":19}]}
