네오슬라이더 I2C 슬라이드 포텐셔미터 -4 RGB LED
(Adafruit NeoSlider I2C QT Slide Potentiometer
with 4 NeoPixels - STEMMA QT / Qwiic)
개요
- 본 제품은 네오슬라이더 I2C 슬라이드 포텐셔미터 -4 RGB LED 입니다.
- 75mm 길이의 슬라이드 가변저항으로 I2C 포트 인터페이스를 가지고 있는 제품입니다.
- 슬라이드 포텐셔미터 밑에는 4개의 네오픽셀 RGB LED가 장착되어 있고, 중간부분에는 작은 마이크로컨트롤러가 있어 I2C 명령을 받고, 가변저항의 아날로그 출력 값을 변환하고, RGB LED를 제어합니다.
특징
- Product Dimensions: 76.2mm x 29.8mm x 21.5mm / 3.0" x 1.2" x 0.8"

Our family of I2C-friendly user interface elements grows by one with this new product that makes it plug-n-play-easy to add a 75mm long slide potentiometer to any microcontroller or microcomputer with an I2C port.
Each breakout is 3" long and 0.8" wide, with a single linear slide pot in the center. Underneath, there are four under-lighting NeoPixels that can display any RGB color. In the middle, a small microcontroller takes I2C commands and converts them to analog reads (of the potentiometer) and NeoPixel control. Goes great with our Stemma QT rotary encoder and 1x4 NeoKey QT breakout.
Thanks to the Stemma QT / Qwiic connectors underneath, you can easily connect using QT cables - no soldering required! There's even four I2C selection jumpers that you can cut to change the address from the default 0x30 to any value up to 0x3F so up to 16 slide pots can all share one chained cable.
To get you going fast, we spun up a custom-made PCB with the seesaw chip and all supporting circuitry for 3 or 5V power and logic. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the rotary encoder or to chain them with a wide range of other sensors and accessories using a compatible cable. QT Cable is not included, but we have a variety in the shop.
You can use our Arduino library to control and read data with any compatible microcontroller. We also have CircuitPython/Python code for use with computers or single-board Linux boards.
