Circuit diagram of an LED as a light sensor is shown in Fig. 1. It is built around op-amp CA3140 (IC1), transistors BC547 (T1) and BC337 (T2). Fig. 1: Circuit diagram of an LED as a light sensor. The ...

This is a story about a successful system that nevertheless failed to make the cut. An experimental LED brightness adjustment is something [Mitxela] explored in a project for a high-precision clock… ...

RGB LED lighting is widely used in home automation, smart lighting, and creative projects. This project demonstrates building an IoT-enabled RGB LED Controller using the IndusBoard Coin V2 and a ...

This circuit shows how to use an ordinary LED as a light sensor. It makes use of the photovoltaic voltage developed across the LED when it is exposed to light. LEDs are cheaper than photodiodes and ...

Build this controller: cd service; qmake als-controller.pro -r -spec linux-g++-64, or qmake als-controller.pro -r -spec linux-g++ if you're on a 32-bit system. make; The generated binary file, ...

This Arduino project controls the brightness of an LED based on input from an ultrasonic distance sensor and a sound sensor. The LED's brightness is dynamically adjusted according to the distance ...

The LED lights have a long lifespan and you probably don’t have to replace them for years. They are also bright enough to help me see everything clearly around my house. Overall, I have nothing to ...

This paper presents an asynchronous boost-type light-emitting diode (LED) driver, integrating an ambient light sensor (ALS), based on a constant off-time control technique. The LED driver ...

This article addresses these challenges by introducing an innovative light intensity control system with LoRa for medium-power LED lamps. In an era when energy efficiency and home customization are ...

Due to the high efficiency of LED sensor systems, ... Diodes Incorporated Launches AL1692 LED Controller/Driver for Triac-Dimmable LED Lamps; Image Credit: ... Benefits of LEDs as Light Sensor. LED ...
