Now, the LED packs will set you back a small investment: there's a listing price of $50 / £50, and the current price of the controller is its list price of $160 / just over £160 so it'll be a ...

The popularity of the ESP8266 WiFi module has a lot to do with its ability to inexpensively connect to the Internet. However, [hwhardsoft]’s stretch limousine environmental control system ...

Zigbee LED Controller A simple carrier card for driving some LEDs via PWM. Hosts an off the ZigBee module. Runs from 5V Derives 3v3 from 5V Has optional 12V rail for the PWM 4 channel, RGB+W low-side ...

To blink the disk LED when a block device is active, you can use the ledtrig-oneshot module and monitor the changes of /sys/block/sda/stat (see scripts/ugreen-diskiomon for an example). If you are ...

The LoRa module is controlled by the ATmega328 microcontroller (U1), whilst the LCD allows us to display the numerical figure, expressed as a percentage of the LED light intensity. Increasing or ...

The MLX81118 also lowers LED power dissipation thanks to its new dual input-voltage capability that optimises the driving voltage for the connected LEDs. This helps to simplify thermal management and ...

This module introduces Pulse Width Modulation (PWM) techniques for Python on the Raspberry Pi. Subsequently, by using PWM we can modify the brightness of an LED without having to change a resistor.

So he decided to add an 8×8 LED module which would display the load for each individual core of his CPU. It looks great next to the illuminated tachometer.
