Another application note from Texas Instruments about ambient light sensors and how to effectively use them. Link here (PDF) Generally, when someone thinks of trying to design a system with an ambient light sensor there are four main concerns or problems that need to be addressed. The most important features of an ambient light sensor […]

Lift: Millimeter-level finger tracking with Arduino and light sensors
Researchers at the UC Irvine and the FX Palo Alto Laboratory present Lift, a visible light-enabled finger tracking: By projecting encoded visible patterns onto an object’s surface (e.g. paper, display, or table), and localizing the user’s fingers with light sensors, Lift offers users a richer interactive space than the device’s existing interfaces. Additionally, everyday objects […]
