多数のLEDを手軽に光らせたいと思ったことはありませんか? 我々はたびたびそう思います。そんなときに使うのがArduinoとTLC5940です。 TLC5940はテキサスインスツルメンツのLEDドライバICで、1チップで最大16個のLEDを制御できます。各LEDを定電流で発光させる ...
An Arduino project that uses a potentiometer to control the brightness of an LED. Reads analog input from a potentiometer (0-1023) and maps it to PWM output (0-255) to adjust LED brightness - roman ...
今回は、Arduino UNO R4を使ってLEDを光らせる方法を解説します。 ELEGOOのLearningキットE3という電子工作キットを使った、初心者でも簡単に遊べるレシピです。 完成品のプログラムも載せているので、安心してください。 ぜひ、最後までチャレンジしてみて ...
DimmingLight is a small library that allows you to adjust the brightness of a dimmable lamp with minimal code. It works with any lamp that supports PWM (pulse-width modulation) signals, such as LED or ...
Abstract: In this paper, a dimmable ac LED driving circuit with high power factor and low total harmonic distortion is presented, which takes series driving via the basic unit mainly constructed by ...
Abstract: In this paper, one AC light-emitting diode (LED) driver with high power factor (PF) and low total harmonic distortion (THD) is adopted, which is added with the proposed switched LED module ...
Supporting non-isolated buck, buck-boost and isolated flyback topologies, the AP1694 enables between 10% and 50% reductions in total BOM costs. Boundary-conduction mode operation ensures high ...
At the Strategies in Light Europe conference, Texas Instruments Inc. (TI) introduced two highly integrated, phase-dimmable ac-dc LED lighting drivers, LM3448 and TPS92070, for use in solid state ...
