The SparkFun LED RingCoder Breakout provides a visual position indicator for rotary encoders. Two 8-bit shift registers drive a circular LED bargraph that displays the virtual position of the encoder as it turns, giving clear feedback on where you are within a range of values.
This RGB revision supports RGB illuminated rotary encoders and operates safely at 5 V. All shift register inputs and rotary encoder lines are broken out to standard 0.1" (2.54 mm) headers.
Key Features
- Circular LED Bargraph Control – Visual position feedback for rotary encoders
- 2× 8-Bit Shift Registers – Drive the LED ring from minimal I/O pins
- RGB Support – Compatible with RGB illuminated rotary encoders
- 5 V Safe – Operates reliably at 5 V logic levels
- Standard 0.1" Headers – All control lines broken out for easy wiring
Package Contents
- 1× SparkFun LED RingCoder Breakout board (RGB)
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
