Turn the knob and the resistance changes smoothly — ideal for volume controls and other audio applications where a logarithmic response matches human perception.\n\nConnect VCC to one outer pin, GND to the other, and the centre pin outputs a variable voltage from 0 to VCC based on the knob position. Hook it up to an ADC on your microcontroller for easy analogue input.\n\nSpecifications\n\n\nResistance – 100 kΩ\n\nTaper – Logarithmic (audio)\n\nShaft – ¼″ metal knurled\n\nTerminals – PC pin\n\nDetents – None\n\nMounting – Panel mount\n\n\nIdeal For\n\nVolume and tone controls\nAudio projects and synthesisers\nVariable input for microcontroller projects\nPanel-mount user interfaces\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6032,"title":"Default Title","sku":"SF-COM-14624","price":6.39,"on_sale":false,"in_stock":true,"available_quantity":159,"option1":"Default Title"}]}
