servo example not working

[hiattp]

Love this framework. led.blink() works fine, but I can't get my servo to respond. The servo sweep example that comes with the arduino software works well so I don't think its the servo. Here is what I'm seeing in the log:

1337133106943 duino info attempting to find Arduino board
1337133106947 duino info set pin 13 mode to out
1337133106947 duino info serial not ready, buffering message: 0013001

readStream: [Object],
_events: [Object] } },
pin: '09',
_events: { attached: [Function] } }
1337133107469 duino write 980901

---

And then it stops. Thoughts? This is my code (pretty much straight from your example):

var arduino = require('duino'),
board = new arduino.Board({debug:true});

var led = new arduino.Led({
board: board,
pin: 13
});

var servo = new arduino.Servo({
board: board,
pin: 9
});

servo.on('attached', function(err) {
console.log('attached');

this.on('read', function(err, pos) {
console.log(pos);
});

this.on('detached', function(err) {
console.log('detached');
});

this.on('aftersweep', function(err) {
led.blink();

this.read();
this.detach();

});

this.sweep();
});

Been a while, but this should fix it:

board.on('ready', function(){
servo.sweep()
});

First of all: really great work :)

Any news on this?
Seems as if the example is still not working.

i tried it with the default port and additionally with a defined port.
my code:

var board = new arduino.Board({
debug: true
});

var led = new arduino.Led({
board: board,
pin: 13
});

var servo = new arduino.Servo({
board: board,
pin: 10
});

board.on('ready', function(){
console.log("onBoardReady");
servo.sweep()
});

And the console log

Any ideas?
Even the examples within the repo does not work - it stops with the same issue that hiattp had.

Looks like this could be your problem?

1348077083735 duino info found board at undefined

It appears it's not finding a board, but the program continues.

If this isn't the problem, I'm not sure. I've been super busy with work lately, and haven't been able to maintain this repo like I had hoped. I'll wire up a servo this weekend and take a deeper look for you guys :)

[Nikolaibibo]

Hey ecto ;)

thx for the quick respond!
it seems as if i've been blind :D

Thanks for your hint - i really appreciate!
Looking forward to your servo tests :)

[Nikolaibibo]

Just to make it clear:

i added a few logs to the board.js to trace the "undefined":

1348149217505 duino usb:: tty.usbmodemfa141 (self.log("usb:: " + possible);)
1348149217505 duino possible: tty.usbmodemfa141 (self.log("possible: " + possible);)
1348149217506 duino possible -> tmp.port: undefined (self.log("possible -> tmp.port: " + temp.port);)

maybe this helps you a bit.
i'm a bit to new to arduino to see where it gets stuck...

thanks in advance :)

Hey, couldn't find anything anomalous. Could you post the circuit you're using?

[Nikolaibibo]

Hey ecto :)
thx for your reply, i really appreciate!

i used a circuit like this:
http://arduino.cc/en/uploads/Tutorial/sweep_BB.png

i tried out a few digital ports like 9, 10 or 11.
my arduino is connected to "/dev/tty.usbmodemfa141"

i also tried the johnny-five solution on git (https://github.com/rwldrn/johnny-five/) and this works fine with this circuit.
Cheers

I'm getting the same error....

[grumpyoldman-io]

Hey peeps,
was anyone able to solve this? I get the exact same "board ready, attaching servo" message.
cheers.
