I've been dabbling around with e-textiles lately and I recently finished up a project that I'd like to share.
I've attached an accelerometer and an Arduino Lilypad onto a stuffed robot toy and made a program using openFrameworks where moving the robot will move a drawing of the robot in the program. Musical notes are also played if the robot collides with balls surrounding it.
The project is more software intensive than hardware, but I thought it would be worth sharing!
