An adjustable potentiometer can open up many interesting user interfaces. Turn the pot and the resistance changes. Connect VCC to an outer pin, GND to the other, and the center pin will have a voltage that varies from 0 to VCC depending on the rotation of the pot. Hook the center pin to an ADC on a microcontroller and get a variable input from the user!
This is a center-tap linear type potentiometer. The outer two pins will always show 10K resistance, the center pin resistance to one of the outer pins will vary from 10K Ohm to about 50 Ohm. The pot is linear meaning the resistance will vary linearly with its position. This is a good choice for general user interfaces.
This pot works great in a breadboard but on a few breadboards, you may have to trim off the large metal anchors.

一個可調電位器可以打開許多有趣的用戶界面。轉鍋和電阻的變化。連接VCC至外針，GND至另一個，並且中心銷將具有取決於鍋的旋轉而變化從0到VCC的電壓。掛鉤中心銷到ADC的微控制器，並從用戶那裡得到一個變量輸入！
這是一個中心抽頭直線型電位器。外兩個引腳將始終顯示10K電阻，外銷的一個中心銷阻力會從10K歐姆到大約50歐姆。鍋是線性的意思電阻會隨其位置線性變化。這是一般的用戶界面不錯的選擇。
此壺在麵包板的偉大工程，但在幾個麵包板，你可能不得不剪掉大型金屬錨。
