usbrelay

THIS IS CURRENTLY IN AN EXPERIMENTAL STATE: It does not yet support multiple boards or other manufacturers. Coming soon...

A Node.js library to control USB connected relays

Setup

npm install --save usbrelay

Usage

const { Board } = require('usbrelay')

const numRelays = 2
const relays = new Board(numRelays)

// Turn all relays off:
relays.allOff()

// Turn all relays on:
relays.allOn()

// Turn relay #1 on:
relays.on(1)

// Turn relay #1 off:
relays.off(1)

Please see examples directory for more examples on using usbrelay

API

relays.allOff()

Turn all relays off.

relays.allOn()

Turn all relays on.

relays.on(index)

Turn relay with index on. Index starts at 1 and goes to the number of available relays. Throws an exception if the relay index is greater than the available number of relays.

relays.off(index)

Turn relay with index off. Index starts at 1 and goes to the number of available relays. Throws an exception if the relay index is greater than the available number of relays.
