Layman’s RGB LED module is an ultra-simple project realized without any microcontrollers. An RGB LED can be driven with a cmos presettable up/down counter. This is accomplished by connecting the three ...

This Linux loadable kernel module controls multiple PWM channels for driving LEDs using the SDMA on Freescale (NXP) i.MX processors. The module supports pre-loading of 'fades' (a buffer of PWM ...

The real-life closeup image of a WS2812B LED is given below. You can see that the WS2812B die is connected to 3 individual LEDs namely Red, Green and Blue using gold wires. The video below shows the ...

This article describes simple constant current driver module with fast PWM input that can be used for driving medium and high power LEDs. The module uses an integrated constant-current output, DC-DC ...

NEW DELHI: If you haven’t yet used the LED modules, then you are missing out something great. It is created to use in the signages and channel letters in the beginning, but today they are prominently ...

Abstract: Since LEDs have a voltage drop specified at the intended driving current, a power source with constant current control is desirable in order to produce a stable illumination. However, this ...

This comprehensive guide shows you how to interface the HC-05 Bluetooth module with the ESP8266 NodeMCU using Arduino IDE. Nowadays, Bluetooth has become an integral part of digital devices, and it ...

You’re going to like [Ivan’s] write-up for this LED computer status monitor. Of course he didn’t just show-and-tell the final product — if he had you’d be reading this in a Links post. But he also ...
