Gomoduino

Gomoduino: notify your colleagues when you are on a pomodoro

But what is it?

Gomoduino provides a traffic light-like sign showcasing when you are on available and on a break, and when you are on a pomodoro. It was made on a couple of afternoons as an excuse to learn how D-Bus works.

How it works

It works in conjunction with Gnome Pomodoro, a Gnome-Shell application for managing your Pomodoros, with presence awareness, notifications, messaging status changes and more.

Gomoduino is comprised of 2 parts, a Python script, and an Arduino firmware. Gnome Pomodoro showcases its state by D-Bus signals. Gomoduino's Python script connects to D-Bus, parses the signals and relays information about state changes to the Arduino counterpart via serial comm. Then, the simple Arduino firmware changes the LED output so your folks can leave you be on your pomodoros.

Here is the Arduino layout:

Here is the Python script usage:

```terminal $ ./gomoduino.py -h usage: gomoduino.py [-h] [-d] [-ns]

A script for inputting gnome-pomodoro's state to serial port

optional arguments: -h, --help show this help message and exit -d, --debug show debug messages -ns, --noserial don't try to connect serial port

```

See docs/ for more info on all of it.

Dependencies

For the Arduino part

Do it with Arduino IDE

(1). $ apt install arduino

or go console style:

(2). Install inotool

a. For Debian based systems: $ sudo apt-get install python-pip b. Install inotool: $ pip install --user inotool (never ever use pip with sudo!) c. Add ~/.local/bin to your PATH

For the Python script:

Debian: $ apt install python-dbus python-serial

Opensuse: $ zypper in dbus-1-python python-pyserial

Also, your user needs to be in the tty and dialout groups:

terminal $ sudo usermod -a -G tty $USER $ sudo usermod -a -G dialout $USER Remember to log off and on again for the changes to take effect.

Building

Arduino part

Do it with Arduino IDE or go console style:

(2). $ cd firmware; ino build; ino upload.

Python part

You might need to change the serial device you are going to connect to.

TODO:

  • [ ] Make a systemd's unit service file for it
  • [ ] Improve host python script
  • [ ] Add time counter BCD display to the microcontroller (currently missing HW, lends welcome)
  • [ ] Make the script a nice python module to install it correctly

Looking for mad skills in:
