Node.js library for using homeduino.
homeduino = require('homeduino')
Board = homeduino.Board
board = new Board('/dev/ttyUSB0', 115200)
board.connect().then( ->
#do stuff
).done()Read a dht sensor
board.readDHT(22, 13).then( (ret) ->
console.log ret.temperature, ret.humidity
).done()Returns all Dallas temp sensors on [pin]
board.readDstSensors(12).then( (ret) ->
console.log ret.sensors
).done()Reads a sensor with [address] on [pin].
board.readDstSensor(12, '12312312333').then( (ret) ->
console.log ret.temperature
).done()Reads all sensors connected to [pin]
board.readDstAll(12).then( (ret) ->
console.log ret.temperatures
).done()board.on "rfReceive", (event) ->
console.log 'received:', event.pulseLengths, event.pulses
board.on "rf", (event) ->
console.log "#{event.protocol}: ", event.values
board.connect().then( ->
console.log "board ready"
board.rfControlStartReceiving(0).then( ->
console.log "receiving..."
).done()
).done()board.digitalWrite(4, 1).done()
board.analogWrite(1, 10).done()
board.digitalRead(4).then( (value) ->
console.log value
).done()
board.analogRead(4).then( (value) ->
console.log value
).done()
board.pinMode(1, 0).done()If a pimatic-homeduino instance is using the board make sure to shutdown pimatic as the board only allows for a single connection.
Setup:
git clone https://github.com/pimatic/homeduinojs && cd homeduinojs && npm install
Hint: If you want to use the client in a production setup you need to manually install the colors
package as shown below.
cd ~/pimatic-app/node_modules/pimatic-homeduino/node_modules/homeduino/node_modules
npm i colors
Start the REPL-Client which is located in the lib directory:
# cd ~/pimatic-app/node_modules/pimatic-homeduino/node_modules/homeduino/lib in a production setup
cd homeduinojs/lib
sudo ./client.js /dev/ttyUSB0 115200
It will connect to the arduino and give you a prompt, where you can enter a
javascript command. To start receiving RF data enter the command
board.rfControlStartReceiving(0) or board.rfControlStartReceiving(1)
depending on the receiving pin used in your setup

The output is colorized by default. You can disable colors by starting
the REPL-Client with the option --no-color.
