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… ...

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 ...

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 ...

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 ...
