rpi-leds-root

Node.js library to control Raspberry Pi onboard LEDs to be used as root (avoiding sudo and auth logging for each command)

Currently tested on the Raspberry Pi 2 & Pi 4.

Usage

Install it

npm install rpi-leds-root

Include it

var RpiLeds = require('rpi-leds-root');
var leds = new RpiLeds();

Commands

Power LED (PWR/red) is referenced with .power.

Status LED (ACT/green) is referenced with .status.

Turn on LEDs

leds.power.turnOn();
leds.status.turnOn();

Reset LEDs to original settings

leds.power.reset();  // Set trigger to `input`
