Arduino Problems

[rupertbuesst]

Heimcontrol is up and running for me on my pi, but having problems with arduino.

I have a macbook which I can use to upload the duino code to the arduino, but there are errors. I'm pretty sure I'm not doing things right. Can someone please help?

I have the following equipment for my home automation setup. Raspberry pi Macbook air Arduino Uno R3 + rf transmitter etc.

Hey rubertbuesst,

You can find a guide here: http://arduino.cc/en/Guide/Environment#uploading

Can you post the errors that you receive when you try to upload the duino code?

[rupertbuesst]

Hi ni-c,

Here are the errors when I upload du.ino:

sketch_oct04a.ino:2:22: error: RCSwitch.h: No such file or directory sketchoct04a.ino: In function 'void handleRCTriState(char, char_)': sketch_oct04a:261: error: 'RCSwitch' was not declared in this scope sketch_oct04a:261: error: expected `;' before 'rc' sketch_oct04a:262: error: 'rc' was not declared in this scope

Thanks!

Also, heimcontrol is an awesome project - congratulations!

[rupertbuesst]

Ok, I think I've worked out how to do it. I wasn't importing the relative files as libraries.

I have a quick question though: Can you turn a non RGB LED on and off through heimcontrol? How do I do this?

Kind regards!

[ConnorRoberts]

Non-RGB LEDs can be controlled through the standard Arduino control plugin as shown here http://ni-c.github.io/heimcontrol.js/plugins/arduino.html

and just connect it to the Arduino as shown http://arduino.cc/en/uploads/Tutorial/ExampleCircuit_bb.png

[rupertbuesst]

Hi Connor,

Which heimcontrol setting do I use please? Do I do it under the Arduino settings, if so which method?

Many Thanks!

[ConnorRoberts]

That's a fair point actually! I seem to remember having it working, i'll have play when I'm home.

I'd try the rc-switch mode with the positive connected to whatever pin and ground to arduino ground and then just leave the Tristate blank or fill it with anything, that seems like it may work.

Will have a proper play later and will probably send a pull request with a proper setting anyway, shouldn't be much work and will remove confusion :)

[ConnorRoberts]

Have added an LED option in pull request #18 :)

[rupertbuesst]

Hi Connor,

Thanks for adding the option!

Now just wondering how I update heimcontrol so I can take advantage of the changes you made. Do I have to format the pi SD card and start again?

Kind regards,

Rupert

Delete the heimcontrol folder, then run

git clone https://github.com/ConnorRoberts/heimcontrol.js.git

and then restart it like you normally would :)

or just

git pull

in the directory (but this will only work when the pull request is merged)

(All data will be safe as it stays in the database)

[rupertbuesst]

Thanks Connor,

I was able to use the git pull method which is awesome.

I'll test out the new feature today. Thanks again for your help!

That may have brought you up to date but it won't include my changes, they haven't been merged yet.

To get my changes, clone my version of the repo for now or wait until the changes are merged :)

[rupertbuesst]

Hi Connor,

In heimcontrol it now actually lets me add an LED, but when I hook it up to my arduino and breadboard it doesn't work. Does there need to be a change to the duino plugin for the addition of the LED feature?

Thanks :)

Just tested on my Arduino (just used duinos debug mode to test before) and it works great, when you wired it up did you include a resistor like in the diagram I posted above? If you did, that'll be why - apparently it's not needed :)

No duino code needs to be changed :)

[rupertbuesst]

Have tried everything, still not working (I'm not using a resistor either).

When I click the LED ON in the heimcontrol interface, and look at my terminal ssh, everything seems to be working, heimcontrol writes to the pin 13 on the arduino where I have breadboard connected with a few leds on it.

For some reason, the arduino isn't taking the commands. Maybe I'll try reloading the duino code to the arduino.

[ConnorRoberts]

Yeah, I'd try reloading du.ino :)

Also, run

ls /dev | grep usb

On the Pi and then if that returns nothing then run

ls /dev | grep -E 'usb|ttyACM*'

And let me know which works :)

[rupertbuesst]

Hi Connor,

Thanks for the reply, the first command didn't return anything, but the second command returned: ttyACM0

Thanks,

[ConnorRoberts]

Okay go into /node_modules/duino and open up board.js

Look for the line

child.exec('ls /dev | grep usb', function(err, stdout, stderr){

and replace it with

child.exec("ls /dev | grep -E 'usb|ttyACM*'", function(err, stdout, stderr){

that should fix it (Source: http://jvrbaena.github.io/blog/2013/07/15/node-dot-js-arduino-raspberry-pi-ii/)

Let me know how you get on :)

[rupertbuesst]

Thanks Connor,

I'll try that. Sorry again for the nooby question, but which command should I use to edit the board.js file? I tried: pico board.js (but I think this is wrong it didn't open properly).

Thanks so much, I'm really grateful for your help :)

Would probably easier to run

rm board.js

and then

wget https://raw.github.com/JvrBaena/duino/master/lib/board.js

[rupertbuesst]

Hi Connor,

It works :) Thanks so much for your help!!

Led is now working for me, can't wait for my rf transmitter to arrive, so I can start playing round with my rc adapters. I'll also do some work with some applescript so hopefully I can make some sort of make do voice control with apple speech, or dragon dictate as I have an old apple laptop with a broken screen which would be perfect for this.

oh s*\ my sd card just corrupted on the pi!

Have to start again :( at least I know what to do know!

[ConnorRoberts]

Just as you got it working! ;)

@ni-c Just noticed heimcontrol.js already runs from a forked version of duino (with another variation of the "ls /dev" bit of board.js), just wanted to point out that this isn't working for everyone and

ls /dev | grep -E 'usb|ttyACM*'

worked in this case, I'd have sent a pull request if that line hadn't already been changed by you, which was obviously to fix something in the first place!

I'd suggest something along the lines of

ls /dev | grep 'ACM|ttyACM*'

but I couldn't say for certain that wouldn't break anything else, so would you take a look please?

[rupertbuesst]

Hi Connor,

Just one more question. How do I start the MongoDB? (say if the pi restarts - I get the MongoDB error when I run heimcontrol)

Thanks,

Hi rupertbuesst,

you will find the documentation here:

http://stackoverflow.com/questions/17901627/setting-up-mongodb-raspberry-pi

Please notice that, i have changed this script to start the mongodb with journalling, somewhere i put:

--journal

[rupertbuesst]

Is there a quick command to just start the database?

I'm using the sudo service mongodb start command, but you need to register as service, simplest way:

cd /etc/init.d sudo wget -O mongodb https://gist.github.com/ni-c/fd4df404bda6e87fb718/raw/36d45897cd943fbd6d071c096eb4b71b37d0fcbb/mongodb.sh sudo chmod +x mongodb sudo update-rc.d mongodb defaults sudo service mongodb start

--- from the get started documentation...

[rupertbuesst]

The problem is, when I turn pi off, then on again - nothing works! The database won't start neither will heimcontrol (cos the database won't start).

Any advice?

:)

[izim]

Do you halt or shutdown the raspi or du you cut the power? If you don't properly shut down the raspi you have to delete /var/lib/mongodb/mongod.lock and then start the mongodb daemon

[bkiss]

I have solved this, starting the mongo database with journalling enabled.

Edit the startup script from init.d (?) and specifify --journal maybe.

http://docs.mongodb.org/manual/tutorial/manage-journaling/

after this, you don't need to delete every time the lock file.
