App note: How to select an ambient light sensor for your end equipment

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 […]
