Grove - Circular LED

This is a unique ring– it has a florid body with 24 controllable LEDs. Maybe it will drive the inspiration out of you to make a glowing magic ring! There is a 1*1 square hollow-out in the middle of this module, where you can place a Grove Encoder in and make it a rotary visual encoder!

Features


  • Circular shape
  • 24 LEDs, about 5.5 mA drive current for each channel.
  • Controllable LEDs with florid effects
  • Grove Interface.

Play with Codecraft

Hardware

Step 1. Connect a Grove - Circular LED to port D5 of a Base Shield.

Step 2. Plug the Base Shield to your Seeeduino/Arduino.

Step 3. Link Seeeduino/Arduino to your PC via an USB cable.

Software

Step 1. Open Codecraft, add Arduino support, and drag a main procedure to working area.

Note

If this is your first time using Codecraft, see also Guide for Codecraft using Arduino.

Step 2. Drag blocks as picture below or open the cdc file which can be downloaded at the end of this page.
