Wearable computing has a long history dating back over 1000 years when conductive fabrics were used. More recently, wearable lights became popular in the late 19th century. Wearable computing now encompasses aesthetic and functional uses such as Google Glass and light-up clothing. The Arduino open-source platform allows users to easily create wearable projects using microcontrollers, sensors, and actuators. Popular Arduino boards for wearables include LilyPad and Flora which can be sewn into fabrics. The Arduino software and online tutorials make it simple to code wearable projects and get inspiration from examples like light-up dresses, solar phone chargers, and smart jackets.
