To build a system where an LED blinks whenever the IR sensor detects an object within its proximity range. This can be used in various applications, such as a simple object detection system or a ...

🔹 Project Details: Smart LED Distance Indicator using Ultrasonic Sensor and Arduino 📌 Introduction This project is a real-time distance indicator using an HC-SR04 ultrasonic sensor and LEDs to ...

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 ...

[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 ...

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 ...

Human-machine interaction has evolved significantly over the past decade through enhancements in user interfaces and smart design. Many of these changes have focused around touchscreen interfaces with ...

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 ...
