This LED rainbow project creates a RGB LED PWM controller with minimal amount of components including a PIC processor. This LED rainbow project creates a RGB LED PWM controller with minimal amount of ...

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 ...

Instructables user [Simon] admits he addicted to electronics. Lucky for him, his wife of 15 years is pretty cool with, or at least tolerant of his need to fiddle with anything that plugs in. As a gift ...

Sunpower’s DAP-04 DALI to PWM converter is designed to provide DALI control in LED lighting applications. The DAP-04 has a DALI input that can accept data from a remote IEC62386-101, 102 or 207 ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

Linear Technology Corp. introduces the LT3761, a dc/dc controller designed to operate as a constant-current source and constant-voltage regulator. It also features a programmable internal PWM dimming ...

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 ...

Linear Technology has unveiled a new pulse width modulation (pwm) generator with 48 independent channels. According to the IC specialist, each channel has an individually adjustable 12bit (4,096 steps ...

The rear light is of utmost importance for road safety. However, since the space required on the electrical module is limited, several functions must be implemented using just one circuit, for example ...
