Light-emitting diodes -- LEDs -- can do way more than illuminate your living room. These light sources are useful microelectronics too. Smartphones, for example, can use an LED proximity sensor to ...

For color sensing in closed environments with no IR light sources, the TCS3x71 Series applications include closed-loop color temperature feedback control in solid-state lighting (SSL) and LED RGB ...

A non-contact proximity alarm developed by Standex Electronics integrates audio and visual alerts—when a trigger element nears the base element, it illuminates an LED indicator light and sounds and ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

The TCS3772 device family provides red, green, blue, and clear (RGBC) light sensing and, when coupled with an external IR LED, proximity detection. These devices detect light intensity under a variety ...

Thanks to the iPhone 4S teardown at iFixit, there may now be an explanation for why Apple restricts the Siri intelligent assistant feature to the iPhone 4S. Apparently, it is indeed a hardware related ...

With the iPhone 15 launch this fall, Apple is expected to bring the Dynamic Island to the entire lineup for the first time. In conjunction with this, the company is also reportedly planning to move ...

LEDs are used in all manner of projects and devices from living room lights to microelectronics. One example in a common device is the use of an LED proximity sensor in many smartphones. That sensor ...
