Example: Simple wireless control of Arduino LED - nilakshdas/baudcast GitHub Wiki
In this example, an Arduino is connected to a system running the baudcast server which commands the Arduino via the serial port.
void setup() {
Serial.begin(9600);
pinMode(13, OUTPUT);
digitalWrite(13, LOW);
}
void loop() {
if (Serial.available()) {
char val = Serial.read();
if (val == '1') digitalWrite(13, HIGH);
else if (val == '0') digitalWrite(13, LOW);
}
}This example uses voodootikigod / node-serialport to access the Arduino's serial port.
var baudcast = require('baudcast')();
var SerialPort = require('serialport').SerialPort;
// Enter the correct COM port here
var serialPort = new SerialPort('/dev/ttyACM0', {baudrate: 9600});
baudcast.from('webclient', function(data) {
if (data.content.led !== undefined) {
if (data.content.led) serialPort.write('1');
else serialPort.write('0');
}
});The web client is also served by the server running baudcast.
