Smiley with leds Answered
I want to create a simple toy for children that can respond to a child's actions.
I want the toy to look like a character with emotions : it can be happy, sad, etc..
I'm looking for a way to show the emotions through the 3D printed shell. I like the way the object in the picture does that. I was wondering if they use leds or lcd screen or anything else.
Do you have any idea ?
