After all, potentiometers are sensors! What's a sensor? Simply put, a sensor is a device that receives and responds to a signal.\n\nPotentiometers are analog input sensors. \nWhile digital sensors deal with values that are either ‘1’ or ‘0’, analog sensor values are continuous. \nAnalog sensors are able to tell us not just whether it senses something, but also how much of that something it senses. \n\n\nIn the case of the potentiometer, it measures electric potential, also known as voltage.\nIt has three pins.\nTwo terminals (labelled 'A' and 'B' in the diagram) are connected to a resistive material, while a third terminal is connected to an adjustable wiper (labelled 'W' in the diagram). \nThe resistance between the two outer terminals is fixed; it is the maximum resistance of the potentiometer.\nThe resistance between the middle terminal and either one of the outer terminals ranges from 0 Ω to the maximum resistance of the potentiometer as the knob is moved.\n\n\n\n20K Ohm Rotary Potentiometer Module\n\n","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5007,"title":"Default Title","sku":"LB-LS1673","price":5.99,"on_sale":false,"in_stock":true,"available_quantity":10,"option1":"Default Title"}]}
