LCD Displaying system temperature    LCD Displaying torrent status

I previously had posted on how to communicate with an Arduino and display messages on an LCD using python. And I’ve been working on Raspberry Pi as well, setting it as a torrent box.

So I thought of hooking up these two together so that the LCD can display the torrent status. I also added two buttons so that I can scroll through the list of torrents. The Arduino is connected to the RPi via the USB, and the Arduino is powered by an external AV adapter. Initially I thought this will be unsafe, but apparently it is safe to do so (http://arduino.cc/forum/index.php/topic,22132.0.html, http://aeroquad.com/archive/index.php/t-1911.html?s=5273633e6fd3970524bf4473996b9f7d) The LCD also displays the current system temperature.

The source code the the python program and the Arduino can be accessed at: https://github.com/slayerjay/RaspberryPi_Arduino

  1. Hi Janith,

    I recently bought a Raspberry Pi and tried both XBMC and Debian and few Python scripts to grab Gmail and print in the terminal…
    But I really like to interfere with HDMI (Video), I want to print top 10 emails on the TV monitor while I watch a movie or something…
    I can’t think of a start, pls let me know if you get an idea…

    Thanks
    Mahesh

  2. Hi Mahesh,
    One method that I can think of is to write a small web application (can be easily done with python +web.py) that will pull the emails and show it nicely on a webpage. Then you can open up the web browser, and set it to run full screen and display your email web application.
    I have done a similar project to display RPi’s temperature over the web. (https://github.com/slayerjay/RPiWebDashboard)

    Some other options are discussed here: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=38&t=29397

    Hope this helps
