GR-COTTON

GR-COTTON is white and round board that has full color LED to link between light and design. You can put a CR2032 battery and write a program via USB cable, so that allows to check the operation using LED and creat a gadget smoothly.
In addition you can program that is compatible with Arduino libraries.

Creating & Writing Programs (Sketches)

Take a look at the GR-COTTON Special Project Page!
Also you can use IDE for GR for that.

 *You can create a sketch on the Web compiler and write the program to GR-COTTON using
    the Kurumi Writer. Also you can use IDE for GR to accomplish the same process.
