Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...
Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...
Microchip Technology Inc. has announced that it continues the relentless production rollout of its 16-bit dsPIC® Digital Signal Controllers (DSCs) with two devices that offer designers performance ...
High-brightness LEDs (HBLEDs) are making inroads into more traditional lighting applications that include a dc distribution system (for example, 24-V MR-16 track lights). HBLEDs are more efficient, ...
The automotive industry makes extensive use of light-emitting diodes (LEDs) in high-beam headlights, brake and position lights, and side and rear direction lights. In an LED driver design, the ...
