Direct Pin
This a prototyping driver.
How To Connect
Install the module with npm install cylon-gpio
Cylon.robot({
connections: {
arduino: { adaptor: 'firmata', port: '/dev/ttyACM0' }
},
devices: {
pin: { driver: 'direct-pin', pin: 13 }
},
});
How To Use
Example using a Direct Pin.
var Cylon = require('cylon'); Cylon.robot({ connections: { arduino: { adaptor: 'firmata', port: '/dev/ttyACM0' } }, devices: { pin: { driver: 'direct-pin', pin: 13 } }, work: function(my) { var value = 0; every((1).second(), function() { my.pin.digitalWrite(value); value = (value == 0) ? 1 : 0; }); } }).start();
